Anyone else that gets sickened by the litter they see on their ride?
Somewhat.
But that is tempered by the occasional gem that I find.
Hand Tools
Hats
Gloves (yes, occasionally I'll find both to a pair)
Found a nice fleece top once, in the wife's size
Lifejackets (I've found Type II, III and IV, adult and child sizes)
Fishing Lures (packs of soft plastics)
Lumber and PVC Pipe in assorted sizes to fit various projects
Etc.
Upon finding a dead armadillo in good condition, I once pedaled a mile back to pick up a whiskey bottle I had passed. Propped up the armadillo with the whiskey bottle on the side of the road. I thought it was funny, but it didn't last a day. The vultures thought it was delicious.
