Sweet site with locations around the world of places that are worth exploring but might not be on the top of a travel guides list.
Urban Ghosts Media, as described on the site as, "a slightly bizarre online magazine about abandoned places, hidden history and alternative travel."
Floyd Bennet Field, NYC
Skull Chapel, Czermna, Poland
Ok so maybe you wouldn't visit some of these locations, but its a interesting site, and worth a look. I don't know about you, but when I travel, I def like finding spots that aren't overrun with tourists. This site will help you find those locations. Tons more pictures and info on the site
