Three rivers is a pretty good place to og to for a fun day. They have two airball fields and i think 13 other wooded fields. The wooded fields are fun and have plenty of barriers. Usually the fields arent equal with barriers and one side always has an advantage. The barriers are big and really easy to hide behind. Although some are useless like the castle in the Castle field. It only has one way in and one way out. If you get trapped in there you are screwed. And it has no windows. But i would say give it a try, even if you are a premium grade team or a just a parent looking to have a good time with your kids. The site is trpaintball.com. So go check it out.
in my opinion the castle isn't bad, you just can't go in and have to hope you make it to the walls first. Just use it as though it were one big bunker, if you ca take the area around that castle then your team wins, end of game. hope to see you there sometime.
