It has been a couple of years since my son went but I remember they had a good number of boys there. Approximately 70-80. Their camp was pretty much like anyone elses and they did the usual, run/field/BP evaluations one day, went through drills with the players at each position and then played games the next day. If you weren't playing, you were working out at the poisiton or BP in the cage. They had the GW coaching staff plus a couple of assistants from other schools helping plus some of their players helping. The coaching staff was nice.
It was cold the weekend my son went and they didn't have a lot of room inside as their clubhouse was small (they did have an indoor batting cage) but I believe they can set up in the gym if there is really bad weather. The field was pretty much a typical small college set up but they were trying to raise money for new grandstand and dugouts. I don't know if they raised the money and made the improvements or not.
I believe they were running the camp to evaluate talent and were not just running it as a money raiser - like some schools do - as they contacted my son and discussed playing there.
Hope that helps.
