It seemed that my body handled it better than it has in the past. I was able to charge on through without suffering pain my my knees, and now that I am back inside I don't feel any after effects either. I suspect the tylenol helped there, but I did the work without it, only took it after.
I put together the pix I took into a little movie. It isnt' finished, it isn't all that good, but it's okay. A learning experience.
