I like browsing around random places with Google Street View. Just found something funny. You know how when you grab the Street View guy and dangle him over the map, all the roads you can view light up blue and the guy hangs there until you set him down somewhere.
If you nose around some of the more remote areas of the desert north of Las Vegas, say on highway 375, the little Street View guy is replaced by a flying saucer when you hold him over the map.
