Dragon Man's - It's in the Springs, but its worth the drive. About an hour's drive Saturday morning.
Paintball Adventures is an awesome facility with sweet fields and (sometimes) friendly staff. They are rather expensive though.
The fields are awesome. They have lots of different types of games to play, and the refs know what works best with different sized groups. The refs are good at letting everyone know when the games are going to start, and makes sure everyone is playing fair and not having troubles with the rentals. Sometimes a few of the refs can have an attitude, but I just ignore the pricks and play.
They have a few speedball fields, if you're into that crap.
The major drawback is the price. You must you field paint also. They gouge on everything, it costs a minimum of about $55 to play for a full day even if you own your own gear!
