Two weeks ago, I turned the big 70. I haven't been on my bike much in the last three years, since I've had 3 knees replaced,,,, No I'm not 3 legged, I had one of them done twice. Yesterday I took the longest ride of the year,, actually the second ride of the year, I did 16 miles and it sure felt good to get the wind in my hair and do some hard breathing.
