Bill,
You don't have to sign up for all three days. If you leave at 5:00 pm Friday you will get to the Seneca just in time(about 9:00 pm) to buy a round. Some of the guys may still be standing, but a few of us will have had enough and we will be outside laying on the ground near the campfire.
Sat. and Sun.will provide plenty of track time and you will be home by 9:00 pm Sun night.
Hope you can make it to the Glen.
Cranky
