Yeah, that's more of a private game, not a rec game.
They don't have airsoft chronos, I provide the ones that are used at our events. Pretty much everything you see used at our events are brought by us, not the field.
I know the field allows private games pretty much any time, but it's nothing like the actual events we host.
You might want to make people aware of that. If some one shows up expecting one of our games, they'll be in for a surprise.
Unless you're providing a chrono and enforcing MIA standards, any event has to be marked with the disclaimer this is not a MIA sanctioned event.
