Heh! That's the first thing I thought when watching the video, "...., I feel old today!"
I remember riding up from SLO to see what was my first MC race. Returning along Hwy 1, I nearly joined the half-dozen amped-up squids who launch into the Pacific after each event. (Noob rider, 5mph too fast, massive target fixation with the edge of the cliff, saved by dumb luck.)
LOL at the absurd wheelies! The GP guys would crash the AMA party, screw about for the first 80% of the race, then make a 3 lap bid for bragging rights.
