Walking in the dark in the new snow - stroke rehab

I think this is going to be a regular occurrence, I need the exercise. We just got 3 inches of new snow, but I was very disappointed that it was no longer snowing. Pulled on my Neos overshoes and decided that the unshoveled sidewalks weren't challenging enough. I headed out to the loop trail in the woods. The flat effect of the dim light on the snow made it even more challenging since I couldn't tell any bumps or depressions. This ended up being extremely good therapy since the depth of the snow required me to lift the left foot properly for each step rather than swing the leg like a log and plow it thru the snow.   There was no way to get lost since I could always see the lights of the apartments and if I injured myself I could drag myself back or compensate by calling on the phone for help. If I'm lucky this weekend I'll cross-country ski the longer loop trail. This is not any type of sanctioned or research validated therapy.
