Last year my nephew took a roadtrip from coast to coast and back, something many of have done in those years when you don't yet have any responsibilities. I guess our Australian Celler members would refer to it as a "walkabout" but here we'd call it a "driveabout". I remember doing a trip of this sort when gas was about .32/gallon!
Anyway, he documented his trip and he has a pretty good sense of humor, so I'm linking it here, it's a good time waster!
Now at age 26 he has a real 9-5 job so it was good he did it while he could!
