GPS has failed!

GPS has failed me! I went to Phoenix with my roommate the other week and we used GPS the whole way, it was pretty cool, it dinged every time we were supposed to be doing something like making a right turn or whatever, so that was handy, unless of course the music was up too loud or something, but even then it will recalculate the route and get you back on track! The other great thing about GPS is that it counts down the miles even till the last tenth of a mile and then tells you that you have arrived :) just in case you missed it. ha ha.Well, on the way home from Phoenix I started to crave taco bell, i know it's my white trash roots coming through, and my roommate did too, so we type into GPS for a taco bell and sure enough there was one 10 miles away! Saweet so we're driving and i'm counting down the miles and looking and looking and then all of a sudden it dings...you have arrived....and joy and i both scream...what?!!!! we hadn't arrived! there was no taco bell! we were furious! but then we wanted taco bell, but we didn't trust the GPS, it had failed us....3 hours later we finally found our taco bell...sans GPS
