I read this thread when it started and thought to myself "What a bunch of boneheads to be so careless to have a bungee get caught in their spokes. I am way too careful for something like this to happen to me." Well, it happened to me about 2 weeks ago as a cord came loose on my front rack somehow and wrapped my front wheel a couple of turns before I could get stopped. This sort of thing really could happen to anyone...
