I have the same problem here in Seattle, only with buskers. Our big annual festival, The Folklife Festival, used to be a great place to run into old friends and have an impromptu jam. Now there are hundreds of professional buskers using up all the room. Since the only reason the festival exists is because the performers play for free, it's irritating to not be able to play on the grounds because there's a bunch of people who didn't sign up for the festival, but are making lots of money being there.
