Yes, we were supposed to lead our first ride for AMC exactly a week after his surgery. He started walking 2 days after the surgery (2 stents put in), 2-4 miles, and then did a couple of flat rides. I got someone else to help me lead the ride, and after the first half of the ride, found him sitting on a stone wall at the top of one of the biggest climbs in Harvard, MA. I was pissed, but figured if he hadn't already croaked, we were good. I was more worried about the incision than anything else.
