As a first time Paintball-player, I attended Action Jack's with a party of ten other guys for a bachelor party. EVERY single one of us had a great time. The field was phenomenal, and the staff was friendly and helpful. The fields had great obstacles/fortification, and the layouts were very good. Nice large fields, that allowed for plenty of shooters. I think we had around thirty players on each team at the end of the day. Lots' of opportunities to shoot and get shot!
Safety was also very good at Action Jack's. Rules and regulations for both games and safety were laid out clearly for everyone, with plenty of signs, as well.
I give this field my highest recommendation!
