Bluebird, I just about exclusively wear skirts and find them very comfy to walk in. I think yoga pants would also work well. Nylon hiking pants are good because they dry quickly. Some of the sweatpants seem to cause chafing, I find, but I am not sure why.

I didn't walk today, but I helped someone transfer the contents of their basement into a dumpster for an hour and a half - that has to count for something. I wonder if I should go for a walk anyway. I really don't feel like it.
