Hallett in Oklahoma many times.
Texas World in Texas, but it is gone now.
Charlotte Super Speedway NC
Robeling Road in GA
Laguna Secca in CA
Indianapolis race track. This one is a bit a cheat, as we were just following the leader and never got above 90 on one long straight. The yard of bricks was cool. That place is huge.
Eagles Canyon in TX. This is my favorite so far. Super smooth, and the turn into the canyon is downhill, off camber, into another sharp uphill. It is very tricky in my old 85 911 with no traction control. If I nail the apex it is fun, if I miss the apex I end up looking at the track out of the side window.
All in my 911. Driven there , and driven home. No trailers involved.
