jamb saws and bike helmets

Today I learned that you can't rent a power jamb saw, aka an undercut saw, in Tucson. A jamb saw is the kind of saw you use to cut the bottom off door jambs so you can slide your new wood floor under them, and you want to rent one because who the heck, besides a contractor, or, say, a rental shop, is ever going to need one of those again? Also, they cost $250 to $300. The upshot is that you can buy a manual one for $20 and steady it carefully on an extra piece of flooring and hope for the best. Maybe it's not that hard - I'll let you know.

In other news, there is such a thing as a traffic psychologist. One rode his distance-sensor equipped bike around a lot of cars and learned that if you're wearing a helmet, cars pass closer than they do if you look irresponsible. Also, the ladies (for purposes of this study, him in a wig) get more room. He only got hit twice.
