Oh, this looks like such a fun thread thought I'd try to bring it up to date and see what other sites people enjoy.
Allison, my sentiments exactly you said it just so.
I am big on fashion sites and shopping sites, but lately have been playing around with Google Earth of all things. My boyfriend *loves* to spend time on there looking at places he hiked in the Grand Canyon. I try to redirect attention to beaches in Europe, but hey we'll get to travel there eventually. . .
The images on Google earth are so clear, and it is free. Well, actually there is a paid access version too. My boyfriend told me the maps are really up to date and a company called Tele Atlas produces them.
