As far as the birthday party part... I intend on doing at least 12 laps (8pm) and think it would be fun to drink a few beers with folks at Basecamp between however many more laps these 40 year old legs will last. Feel free to come earlier, but also my rationale is having some good vibes around when the run stops being fun. At Basecamp I will have my own tent set up with chairs, table, my food/drinks for the ultra. BYOB, I assume not officially allowed but probably fine if you act like an adult.
