Wow you have a heck of a memory! They lengthened the track right before I started racing but I remember them doing all the work on the s turn when I was maybe ten or so. The last straight was a roller and a triple until they started thr rymthm section deal in the 90’s. The track has pretty much stayed the same since then. I like the fact that they did not add asphalt turns. There is lots of action in the first turn because of it.
