Rule of thumb is this with the internet: if you thought of the question, chances are someone else has and posted something about it.
The first step to solving any problem is of course figuring out the places where you can first get help.
In this case, those 2 places would be one: googling the name of the field and looking on their site (or yelp, whatever) and two: looking on a paintball forum.
At least you got to one of the two places.
A heads up on pbnation as well is that the toolbar at the top of the page (not screen, gotta scroll to the top of the forum) specifically for fields and stores; that's where you'll likely find that info as well.
