Travelling light, somewhere in the SW Pacific, 150m ASL, cool breeze, 28 degrees C. No snakes, spiders, or other critters, just mossi's, but even they rigorously kept to a afternoon-only shift.
Different site a couple of days ago, close to HQ. Had already spent a whole day looking for a previous topo surveyor's traverse control iron rods - didn't find any (dug plenty of holes, found plenty of cans and other metal rubble), but late in the day RTK-GNSS re-surveyed a piece of kerb and channel and a manhole using their survey control origin, namely a trig station only 800m from the site. Loaded original topo and re-survey into Civil 3D, 8m difference in position - yeehaa. So went out again, armed with someone else's plat type survey of the same site, reference to the same trig, found control for that, within 30mm of stated positions, over range of 2000m from the trig, including these lovely 1960's concrete control stations (the road used to be the original main highway).
The next one of these stations is about 1000m distant, past the bright roofs, and they are intervisible (as I suspect they all are). Seriously thinking about putting the TS on them, for experience (and somebody has kindly built a shop between my two instrument check stations, so I need another set).
Here's the view on the other side of the hill.
