When I was around 10 years old we used to live on what was basically a building site. Our house was one of the first to be completed on a pretty substantial new housing estate. It was being built, by the way, by a company that had originally made its money running whaling ships out of Leith. Anyway, there wasn't a lot, apart from playing football at The Atlas Park, for kids to do. But there were a lot of empty oil drums on the building site. So, guess what we did? Yep, we used to cram ourselves inside old oil drums and roll down the hill until we hit the wall of a house under construction at the bottom. Do kids still do that kind of thing? Or are they too busy on their smart phones?
