Bare with me: Bear Creek (North and South field), Owen's Outpost, Paint Games Plus, Battle Creek Paintball, Ozark Paintball, Jaeger's Subsurface, Paintball Sam's, Mare Island, Three River's Paintball, SC Village, Woodstock, Venture Games, and numerous other fields from CA to VA through AR and MO.
I just found out about this field when I was purchasing my paint at my local store. I am one of very few that travels all over to try different fields and so far that I have found Valley Thunder was one of my top honors, until they recently closed. I them arrived at UPSN and I was initially impressed the way the staging area was situated. It was basically surrounded by 4 different field but three of them are Sup Air with different configuration to meet NPPL rules.
The whole park at the time I played there was approximately 100acres and is able to expand to approximately more than 130 acres. This does win the claim of the largest paintball park in Nor Cal. SC Village wins the largest in CA. From south SJ it is approx 33 miles to get to the park. The park is owned by a family that basically runs most of the park's operation. With some teens that work in both reffing and landscaping for new field configuration. Currenly they have 3 Air ball, 3 recball (spool, pallet, and urban scenario are present). I spoke extensively with the masterminds of this whole project which are very friendly and are willing to chat while taking a break from digging or prepping the future fields. In fact one of the nearest completed field will include a snake-like trenches with fort mounds for cover. The staging are contains several enclosed canopy to beat the heat, with a portable washing station, and a large porta-potty. The perimeter netting was high enough that the chances of any stray ball flight will not go into the staging nor parking area.
The speed limit on the field is 275 and are fairly strict on it. Self-equipped players cab BYOP and available air for both 3K and 4.5K tank fill. The ground surface is decent in most of the field but the primary tourney field has a soft dirt with is great for diving and being on your knees. There are plans to bring is some softer ground for most of the other fields. Reffing is fairly good the, they know where to look for, that is if the player helps out in the checking proceedure.
Now for the suggested addition and improvements, which is a very small list. I would highly recommend that the speaker of the morning chat should always read the script word for word. Not doing an quick glance and chat it in your own words. This will make the rules and proceedures much more clearer and will cover all of them. I also do highly recommend a target range for players and for refs to be more proactive in moving around the fields perimeter looking for any marks. When I learned to ref a game it was best described as being both a tennis judge and a wrestling ref. On one game I was apparenly hit on the far end of my elbow and didn't feel a thing. When I was one on one with another player we took each other out the same time but then the ref and I realized that there was that hit on the elbow with a different fill color, and we knew it was fresh. So I felt bad and confronted the opposing player to appologize about the missed hit I received. Lastly some one gotta do something about that afternoon winds. I know it may have been a rare instance but almost every shot we threw was caught in the wind. :)
Overall I am beginning to enjoy and find this field as my new high favorite because of the overall layout, organization, prices, and friendly staff.
