I cannot remember who suggested this a few years back for OUr campus, heck maybe it was Groce. Setting up a court somewhere uptown and having anyone come and watch that wanted. I thought it was a crazy idea(still do), but now have seen how it works.
We were in Champaign last weekend, took in the Miami/Illinois beat down, and took in the Street Jam. (

Not much of a real practice, but had some dunks, 3pt contest, band/cheers/trivia/fun/corny stuff. Kids loved it. Seating was at a premium, and if you didn't know someone, or arrive >1 hour ahead, you were standing. But all in all it seemed like a big success. Still not sure if we could pull it off though.
