Bike pods

I was amused the first time I noticed these. I was really unsure about there purpose; there was little else to go on.

I spent many a moment walking past these bulky grey elephant look-a-likes and watched as the became weather worn.

They still tickle my sense of humour for no magical reason other than I have never seen anything go in or out of them. They could be for storage of other things.

What do you think?
