There wasn't that much re-tracking - or at least not as much as I anticipated. The tunnel was still hell to put it nicely. The turnaround after the first drop looked like it only had the top 1-2 layers of wood replaced and it only spanned half of the turn. The tunnel looked to be about the same with only a few layers redone- but I didn't get that good of a look. The turnaround by the station again was the same, and the major retracking was seen at the bunny hill after the turn which did ride quite nice. There was very minimal retracking for the other lower turn around and I did not notice much else. But riding was still like being on a bucking bronco.
