I'll have to look harder.

So far I have only had success at leaving things on the road - like bits of my skin when I wreck - a little DNA. And I have lost a blinky light. And a freaking expensive bike computer that I turned around for and re traced my ride slowly for 2 miles before I found it. I got off my bike and waited patiently for the Suburban full of kids to pass so that I could pick it up off of the ground but it was smushed to oblivion by the Suburban right before my eyes............

I'll look harder for sure. I saw a ziplock bag of cheese curds once, does that count??
