In late summer of 2000 I was in Lake Placid NY doing my very first ironman... it was tough and by the time I started running the 2 lap 26 mile run course it was dark. It went up into the mountains and about 4-5 miles in I start hearing live grateful dead... it was coming from a house about a quarter mile from the road in the woods... totally dark, but just blasting the dead really loud... it was a milestone I looked for the next three times I passed by. Very cool vibe.
