cool. i was on the track in plymouth. i raced mainly in brookefield (hilltop), and stowe before it closed. spent a lot of time at the akron derby downs, marietta, and an indoor track on the west side of cleveland but i can't remember it's name.
i can't remember there ever being a 6 spoke skyway mag. but no argument here. the scramblers came with tuff wheel I's in black when you bought the candy apple red paint job model back in 1980 or so. i had a sales brochure for many years showing all the models but lost it in a fire back in 1990. i always loved the look of the schwinn scrambler.
aside from my 82 skyway t/a, i have 11 early 90's model dyno's. i really like these bikes too. not the lightest or best built frames, but an awesome intermediate. once union pacific bought dyno and gt, the quality dropped.
