We returned from camping early enough that we could participate in Sunday's Nerf Battle. Red Team dominated but it was fun even if we hadn't won. All we had to bring was our "blasters" and eye protection. "Darts" were provided and the games were all organized and mixed between "flip locations" and "tag the marker" (not the official names). I highly recommend joining your local group and having a blast with your family and friends.
Please note, that once you play, you'll want to mod your NERF Blasters which can be a fun hobby.
