I agree that the cost is a problem, as a "older" bloke, with a wife and kids, not to mention the mortage..
But just as hard is the time, Its 2 days a month, and if you add extra tourny's, well thats another day or two....not enough days in the month to find time to spend with the family and play paintball.
Have to go part time!!!!! Or use my pocket time machine, and do both.
