Could be worse... you could be stuck driving a schoolbus with a load of screaming kids going into downtown Houston to someplace you've never been before with a teacher that doesn't know crap from Crisco and all you've got to guide you-- a printout from Yahoo Maps! that's about 2 inches square, zoomed out to the same view you'd have from a Space Shuttle, and obscure and usually totally incorrect driving instructions in the "From: here To:there" dialog printed underneath...
Dude, I got 'em on the bus, and I'll take care of 'em after we get to where we're going, but hey, YOU'RE the one that's supposed to be able to get us where we're going! :neener: Now, leave me alone and let me sleep! :roll:
Seriously, why haven't you invested in a portable GPS yet? If you're doing field trips, even occasionally, to places that you're not familiar with, the TomToms and Garmins of the world are better than a fifth of Jack!
