A Game Fence Is Not As Bad As A Chain Link Fence...
...As far as sighting shooting through.
Surveyed a industrial site a few years ago with chain link fence everywhere. What I thought were good sights and distances were not. Fortunately I had redundant traverse and thorough GPS coverage, used extensions on fixed height road where the corner pins were near the fences. Biggest drive around was a mile. That is the only project I ever needed a least squares adjustment to get right, not just better. Angles and distances were bad, worst where a traverse point was close to a fence.
Along the rear the fence was 10' off the property line which was in an overgrown tree row. I figured I could drive the jeep in between, accepting scratches on the paint. As I go in, I stop to clear to adjoining residential corners and set up bipods, pushing low branches up and over. On the way out I see my roof rain gutter trim in the grasss, but the driver's side door is now up against the fence. Do the squeeze through 3 more times on the project, once that day to pick up bipods and my trim. Repeat twice on another day to set up a traverse point to locate corner points at the calced positions.
The fence go around times were not bad as the parcel was a corner lot. On a return day I set up some high rods to get other traverse points from the questionable ones. Corner ties really improve LS.

Rebars placed in chain link at a 45 make good ladder rungs at interior fence corners, getting back in can be a challenge.
I have thought about how to make rungs that would work on a straight line of clf but have not cracked the code or spent much time on it yet.

One hot day I was manually turning angles down a street. A mail vehicle was working its way down the street. On a couple of sights I could only see past him by a few tenths. The refraction blew up that set of angles. I've seen half a foot vertically looking over a hill in a paved road on a hot day too.

Kent,
There you have it.
Read and listen to the Blessed Bovine and Paul in Pa.
Both are fine engineer/surveyors who have given the intelligent responses.
Bovine also offers some valuable value judgment in asking you to keep your wine at home.
Paul offers very nice anecdotal report of surveying an industrial site n PA for you work.
All of this advice is free for the taking. Do not disregard these propositions.
As they say on PBS, "Thanks for your support."
It is Kent's feminine side that is posting about fences. He doesn't want an answer, he just wants to itch about it.
Meanwhile LoPresti and Bovine are being masculine, that is, offering unwanted solutions.

I can imagine Kent surveying along the eastern line of the Erie Triangle on the NY/PA border.
Andrew Ellicott surveyed the northerly line along PA and NY. To establish the end of the NY claim he had to enter Canada to find the most westerly point of Lake Ontario, he waited at the border one year for permission to enter. Once he was allowed in he made celestial observations to establish the Latitude. He then returned to the US made more celestial observations and established the West line of New York. The Erie Triangle became US land and was then sold to PA.
I believe Kent would have to confirm those observations for any survey work he did in that area. That would be quite a go around, Erie, PA to Niagara Falls, NY to Hamilton, Ontario and back and he would need his passport.

Actually, the solution was perfectly obvious from the beginning. You just climb over the 8 ft. high fence. It's the least bad solution of a nearly inexhaustible number of solutions.
All this doesn't mean that a person can't be nostalgic for the good old days when ranches were enclosed by stock fences that were much easier to negotiate. I'm going to guess that the folks keen to use ladders to climb over game fences have never climbed an 8 ft. game fence with a ladder. :>
The other angle to the high fences is that the typical method of preparation for construction involves running a grader along the proposed fence line to slick things off. That tends to do a good job of destroying old survey markers and occupation, thus adding yet one more hidden cost to future resurveys.

Good lord, why would any sensible person want to survey up there when there is Texas? I doubt you even have any decent Mexican restaurants in Pennsylvania.
I'm surprised to hear there are fences in Texas. Ever found one on a boundary line give or take a couple tenths?
c'mon Kent...
there's probably one or two.

I suppose it's going to boil down to what constitutes a "good" Mexican restaurant.

Actual fences are seldom built that close to line. That fence that ran for thirteen miles wandered hundreds of feet off line in places, for example. In other words, a surveyor has to actually survey, not just flag up some fence posts, give them a good RTK beeping, and practice saying "supercalifragilisticexpialidocious".

That's the chef at the newest Italian eatery. No joke. The entire staff is Mexican.

Or, as likely, from Guatemala.
Naturally, sometimes it isn't any trick at all to get to the other side of the fence. For example, there's this fence:
Wasn't a fence, but in 1963 when I worked for the Bureau of Reclamation we were surveying the route for a new 115KV or maybe it was a 230KV, I can't recall for sure which, transmission line from Lovell, Wyoming to Yellowtail Dam in Montana. We were running parallel with an existing USBR transmission line across part of the Crow Indian Reservation. There was a 1300' span from one structure to the next where the line crossed Dead Man's Draw, which was a deep rugged chasm. By road miles it was a 21 mile jaunt to get from one structure to the other on a non maintained two track road and a good hour or so drive.
Good to here nothing has changed. Not a fence near a boundary in Texas. All they do is get in the way of surveyors.

Actually, you were really asking whether ranch fences weren't within a couple of tenths of boundaries. Now it seems to bother you to discover that surveyors actually serve a function in Texas beyond the fence beeping familiar to you in Utah? LOL.
