Where in Great Britain have I been?

I've visited the counties in yellow. Which counties have you visited? made by marnanel map reproduced from Ordnance Survey map data by permission of the Ordnance Survey. © Crown copyright 2001.

Note: This one only counts places I spent some actual time in, rather than simply driving or taking the train through. And Peterborough got put in Cambridgeshire, though it seems nestled right between that and Northamptonshire and as far as my research tells me is actually it's own entity. I'm sure my UK readers will enlighten me when they return from Sixteen Tones and let me know for sure. :)
