That fits the challenge perfectly. I still don't have a good plan for this badge.
Barb, come down to DC and play Earth, Wind, & Fire music in front of the Air & Space Museum. (I only *WISH* I had thought of that before I did this badge.)
Ha! That would be perfect. :) You could always include that in another challenge - just casually.
Or run with a water bottle. That way you don't make your mask all icky. ;)
