That really is beautiful. I don't remember any that actually had blinkers in the seventies, but I do remember the tall wheel 70cc bikes like that (SL?)
We had an old oil field out in the middle of a corn field. We would ride those bikes through about 100 yards of bumpy, tall mean corn to get to that abandoned oil field. It was about 3 acres of trees with some old truck trails. We had 2 CT70' and 2 of the Sl. There was never any doubt that the taller wheel bikes were far superior.
