Here's an update on my injured knee.
After a week of walking a little then hobbling a lot, I am now hobbling very little and walking much better.  While waiting on car work today I walked around a wholesale store for over an hour, looking at everything.  I even went down rows where there was nothing to interest me.  It felt good to just walk.  Not that my knee is perfectly healed, but at least I can maneuver around shoppers and carts and not have to grab for something every time I turn.  This healing is real improvement, and though it is slow I am very pleased with it.
I had been planning a backpacking trip for November, but will have to put that off until I am comfortable with walking again.  My goal is to backpack at least 10-15 miles at a time, before stopping to camp, and doing the same miles again the next day. I am concerned about uneven surfaces, balance and big steps, like going over logs and fallen trees.
Any bicycling will just have to wait a bit too.
Getting out won't be easy for me next week either, all my time is already scheduled.  Maybe I can go for a morning walk outdoors enjoying the cool temps.  At least the Florida weather will cool down over the weekend with lows in the 50's and highs in the low 70's.  The weather here will be nice.  If you can get outside, this is the time to do it here.  Enjoy!
