where have they all gone?

Here's a sight i haven't seen in a while, a man looking for hidden treasure with a Metal Detector. I remember when i was out playing when i was younger you'd see all kind of weirdo's kicking around. Where are they all now? I'm sure everybody knows who i mean? The guys whos always sitting on the wall outside the shop with his yo-yo. The beardy weirdy who was always at the bus stop when you were there. Even the strange guy that wore the same clothes every morning when you passed him going to school.

Where did they go?

Does anybody else remember these guys?
