When I was a lad & we wanted to vandalise something, we didn't have the luxury that today's kids
have. We had to make our own explosives if we wanted to blow up a letterbox and we didn't have the internet
to find out how to make em.
On a side note, I have one of the boats from work on the hardstand
for 6 weeks and had asked the local engineering company to pop the prop while I was back in town. Came back & found the prop wasn't there so assumed all was OK & went to tell them to polish & prop speed it. They said "huh?", we left it on the shaft. Bugger. Discovered someone had decided it was going to be too easy to steal so had put it in safe keeping until I returned. See, there's good bad. Makes us humans.
