Norwich Bike Tag

Ah! I've had this on my back-in-Norwich to-do list for ages. Well done for beating me to it. A pre-tag for the first post, though? Cheeky. I know this one, but won't be back for a few weeks. This'll be easier than the London one in some ways, but taggers will have to be even more cunning. What's the boundary?

Yeah, I don't own a digital camera, and it was the only relevant picture I could find! Also not sure about boundaries, didn't really think about that, what do people think?
