New Poll Q - Do you wear a HR monitor while racing?

Was surprised to read a blog entry recently where the author mentioned that the hr monitor provided some confidence to push beyond their comfort level and set a new PR. It never occurred to me to wear a hr monitor during a race - just seems too restrictive for racing. I like it for training, but I don't know about racing. And I can't recall ever seeing one during a race, but I also don't recall ever looking for one either. So now I'm curious - just how common is it to wear a hr monitor during a race? Comment/vote in the poll, and let me know what you think.
