While clicking on some YAPC photos on Flickr, I noticed the "(map)" link (I may have been vaguely aware of it in the past, but I actually noticed it this time), and then I was clicking around various photos of Paris (at first YAPC photos, then anything in the neighborhood...BTW I may be visiting next year), then I thought "Hey, why don't I map some of my crappy photos". So I did. I even got first post in a very low density area :-)
I recently tried to make it to the top of the "hill" again (no camera this time though), but it was 90-100 degrees (32-38C), I ran out of water (down to my last pint), and "only" made it to the main divide again. On the map, there are quite a few photos at the peak, but I'd bet that that person drove up...
