Nice shirt! I did a double take there for a second cause we have some vintage double deckers from London driving around where I live. They use them in the public transit system in my city and they've become a bit of a logo for them.
Oh ok, I love the double decker busses, they're great fun to ride, and I'm visiting London later this summer to go to the olympics so hopefully I'll get a few rides in some then .
My town recently sent one of them back to a transportation museum there in the UK. They've converted one of the others to run on natural gas or something like that. It's pretty cool.
