I used to ride a Catrike and picked up LOTS of stuff because you don't have to unclip or get off the bike when you find something on the shoulder. I have found lots of tools. Sockets, pliers, wrenches, hex keys, extension cords, tie-down straps, life jackets (blown out of boats), rope, wire, cable. The V8 decal off someones car (that I put on the boom of my catrike for a while). The best thing I ever found was a 12 pack of cheap beer, unopened and scattered along the roadside where someone set it down on the toolbox of the truck and it vibrated off. I packed the 8 cans I could reach without getting off the trike in my side bag, and tho' it wasn't my brand, drank them all over the next few weeks. Free beer tastes GOOD, even if it is the cheap stuff.
