That's got to be it! There couldn't have been more than one stock car track in Ft. Pierce at that time. I remember it was not far off of the Interstate but can't recall the exit. I do know that we took SR-70 back home because we had a horrible crash on that road early in the morning going back.
Were you familiar enough with the track to tell me the size? I think it was either a 1/4-mile or 3/8-mile like GGS but no bigger if memory serves.
Thanks a bunch for the info palmbayer, I appreciate it!
