In reply to fred99:
I wouldn't be so blase about Ambleside and Windermere: Barrow's figures may be atypical because of their testing history but there's no reason to suppose that the South Lakes figure isn't representative and that's where most tourists will end up.
As for the notion that the locals stay indoors while the tourists clog the pavements, footpaths and bridleways- that's a suggestion I wouldn't like to make outside the confines of the internet and certainly not one I'd broach in a crowded meeting.
