There is an old hay barn next to my place, still full of hay from many years ago. A lot of boards are bow out and loos, and some broken off.
A woodchuck makes his home in there every year in a spot where two boards are broken near the concrete foundation wall. This foundation wall is probably 3ft high, and his hole is above that a ways in the corner of what use to be four square bales...he jumps up and dives straight in that hole, no problem!
Craziest thing I've ever seen one do.
Otherwise, I regularly see them sunning on top of some big brush piles out there near the barn.
