Have a look at this

The only time I've seen a penny farthing, it was jumping a red light on Sloane Street.

And I think the rider was wearing tweed too..

That reminds me of one Sunday morning last year when I was riding towards Embankment, I saw a, errr, peloton of tweed wearing penny farthingerengers riding up the Mall. Even had the facial hair that you'd expect an authentic penny farthing rider to have! :)

Must have been about 8 of 'em. They did look quite impressive! I was tempted to turn round and ride and have a chat but didn't in the end.
