The variety of fields is excellent and the fields themselves are quite fun to play on. The staff is poor overall, as is the walk-on group division. The field paint only rule is not actually enforced, but the field paint is not that expensive. It is around $70.00 for a box of decent paint.
I have only done walk-on play on this park. All the people with their own guns go into the 'intermediate' group which is also the de-facto 'advanced' group. But nothing too wrong with playing with people better than you, that's how you get better. My largest complaints are the refs and the time between the games. In walk-ons there are obvious cheaters who up their velocity and wipe paint yet I never once seen a ref do anything about it. The time between games is just too long, in some cases half an hour or more.
As the fields themselves about half the fields are derivative but even the derivative (woods, speedball, etc.) but even those fields are better than your average derivative fields. They have some innovative fields like "the village" which is one of my favorites. "Trenches" is another example of an original field.
The personal aspect just isn't there, I'd love to give these guys a better rating but they really need to work on their walk-on game. Some of the regular players are great but there are enough that wipe and otherwise cheat to ruin it for everyone else.
