It's about two miles from there to here, and there's some nice scenery along the way. The only drawback is having to allow enough time to get here, and having to do it again at the end of the day whether I feel like it or not. (There's always cabs and buses in a pinch, I guess.)
I figure the walking is an easy way to help make up for the computer screen I stare at much of the rest of the day. We'll have to see if this idea survives once the mercury tops 90, though.
