I've found lots of hand tools. Last fall I watched a guy lose a DeWalt 20v recip saw off of his bumper, then followed him until he stopped. I walked up to his window to hand it to him and he just said "huh", grabbed it, then rolled his window back up. Ungrateful prick.

I lost one of my boat chairs last year on my way back from caribou hunting. The damn thing had been in the boat for thousands of miles all over the state, but somehow flew out on a flat stretch of road 3 hrs into my trip. Before I could get turned around some old boomer in his land yacht came cruising by at a about 50mph with 15 cars behind him. I watched him smash right into the fuggin thing and send it flying out into the rhubarb. Never even touched his brakes. No idea how he didn't see it, but I'm sure he saw some damage when he got where he was going.
