OTP is probably hands down the better fields I have played at. I just finished a tournament there, and must say, the field were well set up, and reffing was top notch. I have recballed there a few times, and just as in the tournament, top notch refs.
Pro shop is well stocked. Field fee is a little high (i think $15). They are FPO, and the paint prices are up there a little, but not too bad, high grade goes for $53 (X ball Silver).
Safety wasnt STRICTLY enforced, but then again, there werent too many people there on the days that I was, and everyone was experienced. No one really violated any rules, and this could be the reason I didnt see any enforcement. I know they have drinks, food Im not sure of.
