*Come to the ride overprepared.
*Bring a cycling computer.
*You must wear a helmet.
*You must sign a waiver before you ride.
*You must wear a race number on you or your bike some where. It helps with checkpoints and the finish, and makes you look geeky cool as you ride.
*Wear cycling shoes that you can walk in. If it rains a bunch, there is at least one dirt lane that won't be rideable.
*Have a plan in place for someone to pick you up in case you DNF. This is a self-supported ride and you are responsible for yourself.
*Bring a change of clothes for after the ride (even if it doesn't rain).
*Saturday night campers can just pull on in to the farmers property and set up camp. I won't likely be around until early Sunday morning.
That should cover it. It's not complicated, but be smart. It's going to be a great day to ride a bike!
