I was working, in fact. I'm taking a break now, and resting my back. Spent waaaay too much time on inner campus with the Tennant. (For those who've not heard me pontificate about this particular machine, it's a diesel-powered vacuum, about the size of a VW Bug, but now as cute. And noisy. And smelly. But it beats cleaning up 500 people's worth of spilled popcorn and crap with a broom.)
