So many people writing about it, thought I might throw my 2bits in.
Let us start with the CONS:
I played, I belive on the 1st of Jan. 2004, a massive game. It was much like a real war, the lines pushing both ways. Those games are chaos, seeing the enemy will get hit, walk out, then walk back in behind you and shoot you in the back. My bros got hit, then I got a little retribution on their behalf. They don't have the staffing for enourmous games like that, I never saw a ref once. Those big games are a waste of money.
I was but a lad of 14 the first time I went, and to this field it was. As a virgin to the sport, I was terrified, but quickly developed my sense of survival, and incorporated the immense and wonder fields to my strategies. Many years later, I still enjoy the natural and man-made art of the field.
The playing fields are huge and various. I reccomend this course. I am not an expert on paintball quality, but the paint was fine for me. I am not into speed ball so much, but the two courses they have set up are good (I capped my brother and father a few times).
