Just as a pre-event safety briefing.
Please bring the following:
Water: Just because its cooler at night doesn't mean that you don't need to hydrate.
Food: Don't count on being able to purchase food, bring some sandwiches or something.
Flashlight: Its dark, use your brain.
First Aid Kit: Just in case
BBs: Its a long OP, and its dark so I expect most of you will try to pop anything that moves....
Integrity: Call your shots, play fair, and have fun.
and
Good attitude: You will immediately be asked to leave if you start trouble, I don't get paid so I am not babysitting tempers.
