Ian,
You have a very valid point, I have to say ,I thought of the consequences every
time I went into turn 4 at Poconco at well over 100 mph in my 7, ( North course).
I have also run the oval at Pocono and Loew's Motor Speedway in my Mustang
Cobra at 130 +. I think back on it now, and I think good luck, average skill, and
good car prep, and common sense keep me off the very hard retaining
walls.
Point well taking.....
