"We're really only letting clear bags through our gates here. If you have a small purse or a fanny pack or something like that, that's OK," said Rick Farman, a co-producer of the event.

Now in its 11th year, the festival also showcases local restaurants, wineries and breweries, along with local art, comedy and a series of speakers.
