Yesterday's air quality was "yellow" which means no outside burning and that you should avoid strenuous exercise. They also suggest to limit your driving. Boise is not known for it's public transportation and I had an appointment about 8 miles away, so of course, I rode my bike. I did ride slower than normal so I wasn't doing any heavy breathing but couldn't help but wonder how cool it would be if on a yellow alert air day NO one was allowed to drive, of course that isn't going to happen in the near future but how great would it be if everyone had to walk, ride or take the bus.
