I was recently there as part of a bachelor party and had a great time. The owner was more than helpful, especially with the guys not familiar with the paintball experience. We felt like we must have annoyed him with the constant requests to replace helmets and other items but he was calm and friendly.
The fields we played on were great, we played on 5 different courses between the 7 of us as well as against other teams of 8. The staff was great too, keeping an eye on everyone to make sure things remained safe and fun. They even gave individuals tips on how to improve their play, a great touch.
The proshop had just about anything you'd want, I especially loved the grenades (I left one in the woods so watch out). The prices were reasonable and we didn't feel like we were being taken advantage of in any way.
My only issue was the helmets. I wish they were of better quality to prevent fogging, it was a major issue in the dead heat of the afternoon. If you can, there are a few great ones so make sure to try and snag them or bring your own.
Overall, I think any one of us would gladly go back to the Nest.
