Stumbled upon this on VG. Not really a big fan of "stalking" but since all those guys are dead I think it’s an interesting collection. Scrolling down through the maps, you realize how nearly all of them strived to keep a low profile, with Castellano being the most obvious exception (that thing is a palace!). Accardo’s home wasn’t exactly a shack either.
