Yea man, I can testify to that! Having ms I'm no stranger to the VA hospital system. It's service connected .anyway I rode up to the MPLS hospital, before I had a sidecar, and the doc noticed how great I was feeling. After I told him it was because I had ridden he told me to keep doing it. I asked him to put that in writing, he declined. Hope that new knee gives you many more miles!
