If you look at the bulletin board on the right as you enter, you'll see a clipboard with Gunnar's petition to cancel the festival. Not surprisingly, his name is the only one on it.
Nancy is more than willing to pick up the pen attacked to the clipboard and sign this petition, though I can't think why. Should you sign or not?
It's up to you -- I never found that it made any difference one way or the other. It kind of appeals to my contrary side to support the lone crackpot, though I can't see any good reason to stop this tiny town's only way of making money.
