Ive been playing Paintball seriously for about a year now, and its without a doubt the funnest sport ive ever participated in..
it gets a little expensive when you play at the tournament level, but there is nothing I would rather be doing.
we have our own NPPL field now, some sponsorship to offset costs and whatnot, so it isnt too bad..
only thing I regret is not fining the sport sooner, I started at 26, wish it would have been 16.
