My theory, which is mine (ahem), is that you can learn the important touristy rudiments of a language by switching your GPS to it while driving around in the US. Distance measures, numbers, left, right, straight ahead, street, east/west, plus a solid feel for pronunciation, word order, and cadence - it seems excellent. Has anyone out there tried it? I don't use one myself.
When driving back from Parris Island my two Romanians found it uproarious to listen to the GPS direction in their language while driving in NJ. Drept inainte.
