Thanks for your response, butterfingers. I have been thinking about walking with a ukelele, since you mentioned it, and I am convinced it has a lot of potential. I will give it a try someday soon.
I did not realize you live near the canal. My home and church are also near the old canal. In fact, they are starting neighborhood watch groups and our area name is "the canal district."
As far as top walking goes, I can report that I am slowly working it into my routine. The short circuit is a very durable top and it is easy to keep in the pocket of my jacket or my pants pocket. I have pulled it out for half mile sessions enough times to be over 3 miles of walking and I find it very helpful when doing stairs. They go so much easier as I am thinking about the top and not the pain in my legs. So far I have gone over a hundred flights with a top spinning in my hand. I am continually surprised at how many people are more willing to talk about tops when they see me walking.
