[Greyzone]

looking really cool, i also kinda did this stuff a while ago whilei was living in dresden.. i did parkour there and you get to see a lot of stuff you normally dont, actually had an abandoned big house (former videothek if that the word in english) never made it to discover it since every window in the groundlevel was closed with barricades
did some of that exploretion in my old school too, at that point it was used i was there daily, still it was exciting going in there while night time, the school was old, so some windows didnt close properly etc. was hell of fun and excitement
