Just got back from a hike on an old rail trail with the family and it's always fun to see what turns up. We found the usual stuff like spikes and a rail plate, but then I found a couple of channel iron pieces. I'm not exactly sure what they might have been used for. I wished I took one home or at least a photo to share here, but I was enjoying the moment too much! It got me wondering, what's the best or most interesting thing you've ever found on an old rail trail?
