It wasn't all that busy on the Friday. In fact I was surprised by just how few people there were. I didn't see the action on Saturday but if Friday was any indication the event has tapped out and will either stay at its current size or start to taper off given booze events like Beer Week, Brewery and the Beast, Art of the Cocktail, etc competing with GCBF.
There's only so much people can spend, especially with GCBF, Ribfest, Brewery and the Beast, Rifflandia and Art of the Cocktail all within about one month of each other, and Swine and Vine is in there somewhere too, plus Feast of Fields or whatever it's called.
