The first sports car track I drove at was Bridgehampton. Ran there in late 60s into the 70s.
We stopped by Thompson one time just to see it, but there was no races going on. It was a pretty good road racing venue (it still runs roundy-round stuff).
I remember going to Marlboro as a high school kid. Penske and Donahue would run there. Lots of others too. Two years ago, my club ( VRG ), had a Marlboro Reunion at their Jefferson 500 event at Summit. Lots of old Marlboro racers came including Col. Joe Hauser and Ray Stone (both guys I followed when I was in college). I actually got to race in the same small-bore race with Stone and his Bugeye....pretty cool.
Sad that these places are gone, but there's several new tracks on the horizon here in the northeast, so all isn't lost.
