and the party started the weekend before with the race...We missed Woodstock, but we did make it to Watkins Glen 4 years later. We rented a Uhaul 30 ft box truck and drove from Boston with about 20 people. It was pretty good...climbed a 30 ft fence to get the backstage of the Allman Bros. And yes, it rained as well, and that’s when the whole thing went to hell:)
But it was a huge event...over 600,000 people...at the time the largest rock concert ever...much larger than Woodstock.
