One major issue with this is that not everybody wants to pay money to have a meet. And if they do pay the entrance fee, they'd rather be going around and seeing everything than spending it doing something they could do for free.
I, for one, don't plan to go to Boxerfest again. I didn't feel like I got my money's worth and I don't like large crowds.
I think it'll be in May again. April is just too cold (as we discovered the first two years of the meet).
The location will be the same. Whole Foods has food, bathrooms, ample parking, and no problems with us being there.
