I enjoy wheeling abandoned railroad corridors. You find all kind of neat stuff. Old railway equipment, signal stands, concrete bunkers..
You do find all sorts of neat stuff around railbeds. Haven't found it by wheeling, but hiking down near an old rail weigh station (Heh, sounds like railway.), we found all sorts of odd things. Steel cups and plates, a couple old shoes, even a rotted old hat that looked like one of those conductor hats. Last time down there we found a big pile of rail spikes and retaining plates. Might not seem like a great find, but still, they are pretty neat. Plus, any time you're near tracks, look for the shiny silver-ish porous rocks.
Stuff I found wheeling.. Mainly old garbarge that people dump out in the IP here. Washers, toilets, sinks, shingles, roofing supplies, nails, beer bottles, old toys.. Probably the coolest thing we found was the old boom. Found it years ago.
Looks kind of like this:
Big, rusted, and red. Don't know if the boom still exists out there, but you could see the drag lines for it scattered everywhere. I'll have to get everything in the jeep fixed up and find it again, and take some pictures. If anyone is around Nanticoke, PA, and they can get out the IP, the last place I remember seeing it is past the sand pit on the main drag, past the lake-puddle and hill, and off to the right down a sandy-silt path in a clearing. Here's to hoping no one hacked it up or shot the hell out of it more.
