Look what we found:
A trestle bridge built in 1931 for the railroad, now used as a foot bridge across the New River in the vicinity of Hiwassee, VA.
We left at about 9am and got back to the cabin a bit after 3pm. No rain...except for the last 10-min just before the bottom fell out. See weather map below. We were lucky on a day threatening 80% chance of rain!
