Paintball Adventure Park (Taneytown) and Route 40 paintball. Taneytown ranks neck and neck with Robinhood and Rt 40 a distant second to both.
I love Robinhood. I started playing there and I go back every weekend. The airball (and new hyper/spool fields) are changed up every now and then which makes it more fun. Another thing i like about this field is that on any given sunday you have a decent chance of finding Ether and Image guys about. If you want to move up to a tournament level player, finding guys like these who are willing to show you the ropes is really nice. I would love to see better airball bunkers (ie NPPL ish), they are on par or better than other fields but i am partial to this field but everything can always be better.
