Frozen pipes! Help!

Folks, Remember the old saw "The cobbler's children have no shoes?" Well, this do-it-yourselfer had just enough smarts to go next door to his vacant rental unit and set all the faucets to drip, but not enough to do the same thing in his own unit. Ergo, my plastic pipes are frozen. (Yes, before arriving at this conclusion I confirmed that the city had not surreptitiously turned off my water service.) I've turned on all my faucets to full blast and, of course, nothing's coming out. Not even a gurgle. So, since I have a good sized crawl space, I wonder whether I should just bite the bullet and go there and tap on the exposed plastic pipes from where they enter my unit through the concrete foundation wall all the way to where they actually enter my living space. Is this a stupid idea? What should I do, then, if that's not a good idea? FWIW, I really, really have to go to the bathroom. (Yeah, I guess I can just go next door to my vacant unit, but I don't want to go there and find out that the dripping faucets weren't left dripping enough. The devil you can see is not as scary as the one you can't see.) Jeffrey W.
