Moe, this is a good thread.

1. Chainguard bolt here in town; promptly tossed the chainguard into a pile of stuff in the garage and just left it there.
2. My favorite bungie cord on the way to work. Saw it in the road on the way home that afternoon, but didn't stop to pick it up.
3. Oil pressure warning light lens. Still have yellow electrical tape over the light two + years later.
4. Front fender bolt disappeared on the way to NY in 2007...still need to get that replaced too.
5. Cell phone. Dropped it while putting my helmet on; forgot about it until I ran over/spun out on it leaving work a minute later. It looks rough, but still works.

I'm sure there are other things, but I either didn't even notice or have just forgotten about them. Does losing electricity on the way home from NY this year count?
