To me, all this looks about as tidy and presentable as a trip through nasty brambles and over barricades in to a perilous window left open, graffiti and fresh fire evidence with a chance of meeting a vagrant living there.
I should stand on the sidewalk muttering something about calling the police on you lot. Fuckin urban explorers.
You just need your brain re-wiring.., that's all. Mine's wired for code and tripping over brambles.., which reminds me, I need to schedule a Sheffield UX trip soon with the boys.
