Yep, derbyshire seems to be particularly bad for them. Manchester has quite a few dotted around on those annoying 30mph main roads that could clearly have been turned into dual carriageways too. My impression is that most of the country got a job lot of gatsos
Judging by the speed some people go through them there must be a website somewhere showing all the ones that are turned off?
Not that Adams have to worry about such things... I'd be struggling to keep up with that milk float too
