You're meant to get bumps and bruises as a kid! The sites were fairly safe. It was just houses, so everything was bolted down well. Falling or metal edges were the only real dangers. But now there's temporary fencing up at every construction site. I think some people have realised how much unguarded construction materials are worth.
Janggut, you must have had somewhere that was what it wasn't when you were playing as a kid?
