Base protection device, it's always a concern how to secure the base with livestock in the area:

Two more 1/4 corners


And local wildlife:

wonder how that poor coyote got his foot caught in the fence?
I think it was placed there as a warning to other yotes...
Nice Stones!
Love your base setup...
Loyal
how much did you have to pay for the corner-locating bird. I'd like to buy one....
Must be fooled by the 'no hunting' sign!
C.
That must have been one BIG bird, or the stone is smaller than it looks. :-$
Spacing between the pipes on that cattle guard must be wider than any I've ever owned. But, you are correct, it would take a leaping deer to take that station out.
I don't know, first thing I thought of was the old bull strolling up and rubbing his head on that corner bar and flipping the whole thing over. Just because he could of course.
Yeah - If you fed the bird orange berries it would be even better.
looks to be a ways to the nearest mountain ash. That would get the color right, but the bird would be so drunk it couldn't tell a corner from a goat stake.
