On a century ride last year, I was riding in a line and all of a sudden the guy in front of me pulled out, but I didn't. At that moment I ran over a freshly killed skunk, got his scent gland head on, damn! The guys wouldn't let me back in line, said I'd make them sick from the odor. Took about a week to rid my rear tire of the stench, I would have replaced the tire, but I didn't want to touch the thing.
