>>I'm getting knee surgery on the 8th, so I've got a month off work. <<
In 1989 I had an ACL reconstruction and was given 4 weeks to recover. After two weeks in bed sucking down Percoset and then Advil I said F this action, suited up and returned to my job as a Mercedes Benz salesman. We had a showroom with three flights of stairs to get to the roof parking lot to retrieve cars for test rides with customers. I was sailing up and down those bad boys on crutches in no time.
Beats the hell out of lying in bed. But in those days I didn't have Versus cycling TV to entertain me. I might have stayed home in that case.
And it was the rehab from that injury (starting with cycling about 6 weeks after the surgery) that led to my cycling addiction 18 years ago. Good luck with your surgery and rehab....
