Did anyone ever take Riverside from 101st until it ran into Sheridan (by that point I think it's called River Rd.), going 70+, back in the day?
Yes, back in the early 80's (82,83,84) several of my friends and I used to see who could get the quickest run down that stretch. At that time the starting point was just south of the Jenks Bridge (Riverside Drive ended at 61st) and the end was 121st and Sheridan at the stop sign. At the time I had a TR6, a TR7 and a modified Jensen Healey and would easily be doing 100+ before taking the turn onto 121st. I think about 70mph was the fastest I took the turn.
Some one mentioned doing the Tulsa to OKC run on the turnpike. A couple of times I made it in roughly and hour. Always loved the look on the face of the attenant when they stamped thee time on the card to hand back.
