Safety - is ok, when I was there they only had about 2 Ref, but they did try to their best to remind people to put on barrel plug and keep their mask on.
field - some what unkept, but playable. They have about 5-6 fields. Do not play the 'BUS' field.
price - cheap compare to other in NJ, $25 bucks, $30 if you bring your own paint.
Overall I do like the place because if you bring enough people or can meet some players there then you can start your own game with out ref. It's kinda neat cuz then you play at your own speed. But if you want a more organized game with actual ref then this might not be the place for you. I'm giving it a 7 cuz I did enjoy playing there.
