I have only played one other field that I play with my friends, but we can't ever get more than 6 people. This field is much better with a lot more people.
This field is a great field that I have been playing at about once a month for the last few months. It's a lot of fun and a great place to call your "home" field. In terms of safety, everyone seems to wear their mask and use chronographs. A few months ago a guy was shooting at around 350 fps, which made a really bad bruise and there was an argument as a result. For the most part the field is very safe, except when teams are there they tend to get out of control. The field is free and you can purchase air or paint from people there. There are refs to call people out, and they do a good job. The people are very nice and helped me out my first few times there teaching me about my a5 and the field. Overall, great field, especially for $0. Come on out and I might see you there!
