Panoramio. I used these photos in Google Earth heavily before every travel. Street view is a poor replacement, I'm missing so much stuff that was off the road.

Panoramio. I used these photos in Google Earth heavily before every travel. Street view is a poor replacement, I'm missing so much stuff that was off the road. I could see what the beaches look like, what's the terrain at some point, path through wood. Heck, even just frequency of Panoramio photos at some location would tell me what's interesting to see there.
