This didn't happen commuting, but it was definitely strange.
I was cycling from the Hook of Holland to Rotterdam, along the bank of a waterway, on one of the many very good Dutch cycle paths, when I saw a bloke in a deck chair at the side of the path. At the time, the weather was like this:
As you can see, it was decidedly gloomy.
I get closer and I can now see that this guy is massively tanned, I mean properly mahogony, it's clearly natural, but this guy is practically black (but he was such a colour that it was clear that he started off white)
As I got closer still I noticed that he was in around his late forties or fifties, and also what he was wearing, a yellow banana-hammock. Yuck.
