No I was riding my Schwinn Continental 30 miles North, in Annadell that day...well back in 1977 it was the Ledson/Richardson Ranches. Still in the dirt, but no fat tires for me back then. I think I was running gum wall tires. I am kind of diggin that Sting Ray type seat....gets your weight back and still be seated.
Oh yeh, my hair was longer than the guys in the picture. I bet Mike's was too.
Dean not kidding.
