These were really great links but now they are abandoned and missing. Disappointing.

Rooftopping is not about hanging yourself from the edge of a building.

Skywalking has been promoted in the media as rooftopping, incorrectly. Urban exploration is not about taking silly risks with your life. Urban explorers take photographs, are careful as they explore, don't litter or vandalize and they make it home again to upload their photographs. Taking photographs is not to prove you were there, or show how much of a thrill seeker you are. The photos document the place you visited, not the fact that you, in particular, were there. Rooftopping is not performance art. Some explorers like to be underground in tunnels, drains and other types of big holes in the ground. Some (maybe the same people) like to be far above ground, to see everything from a new angle and look at all the city lights. The first rooftopping photo was taken in Toronto, Ontario. The photograph showed the city far below with the photographer's shoes hanging over the edge of the tall building they were sitting on. (Note, sitting on, not hanging or dangling from). If you enjoy dangling yourself from a crane join a circus or take up construction and learn how to do it safely. Have some care and respect for yourself and be here (relatively undamaged) for your own further adventures, tomorrow.
Sorry to see it closed. I loved the idea. I still draw the odd map, long hand. None of mine seem important enough to post though. You can buy the book created by The Hand Drawn Map Assocation, with the best or most popular hand drawn maps. The Hand Drawn Map Association of Canada - Maybe it will go somewhere.
Source - Jaynee Cakes on Cakes Decor I like all the detail. Plus, it's not the typical black mansion/ castle looking house drawn up to be spooky. This is a house you could find, abandoned somewhere not far from your own street. Too bad there isn't a photo of the back of the cake. I hope it has a decorated back, not just a front for show. I looked up her site, Jaynee Cakes. (Somewhere in the US. I did not find a location, just a phone number).
I like the vintage postcards even better than the photographs. I collected postcards for years and the older cards were always my favourites, when I could find one. Likely that postcard collecting has stayed with me. Some of these buildings (if not all) are demolished. The waterfront image helps to show where they were.
This was the first house I photographed with a digital camera.  Both the house and the camera are gone now. I bought a new camera, but the house was irreplaceable. To me the old houses become stoic individuals, one of a kind, the longer they remain abandoned. Please don't vandalize, salvage, or take souvenirs. (I partially exempt garden plants because they are living things which can bloom again).
I found Jonas De Ro at a site giving free downloads for wallpaper.  I've since lost that link due to a couple of problems with moving my sites from WordPress. But, I did find the links on Deviant Art, Facebook and his own site.
