I'll jump on this hijack to say how much I love The Glen as well.
First time I drove the track got out of the car with tears in my eyes. It was everything a great race track should be in history, technical challenge, turn variety, and elevation change. The blue bushes made you feel like you were an F1 driver in a Skippy car carving up through the esses.
Everyone remembers that pile up Gerardo was witness to but nobody remembers who won the race.
I was fortunate to win three times there and had the great pleasure of doing everything I could, but ultimately failing to catch Doug on the day he won there. Pete Argetsinger's house, At least two great restaurants on the other side of the lake. All the stuff everyone else has mentioned... It's always a special treat to have the run of that place. :-)
