I like the last weekend in August because I know CCU will be back in session by then, and so will high schools in the community, so that would bring in more students in my opinion. (Aug. 26 - 29th)
I agree with tiger on this one. the last weekend in august would be best. july 4th was one of the worst weekends you could have done it. Also Im pretty sure you could set up wth freestyle a gay day type thing.
