Thought this was a neat idea. Dont think the locations are quite so detailed for the UK, but have a look and add yourself.
Make sure you add a "Shout-Out" to your entry, otherwise it doesn't log it.
Apologies too if it can't get your exact location, just get as close as you can. The locator sometimes takes a few seconds to autocomplete your town.
(It's true, I do have far too much time on my hands at the moment)
