A farmer says he sprayed slurry over dozens of luxury cars parked illegally in his field because trespassing urban day-trippers from the city don't respect the countryside.After years of putting up with tourists leaving their vehicles on his land as soon as the sun comes out, this week sheep farmer Hogg Hodgson finally snapped.The furious tenant farmer, whose family has run Rydal Farm in the Lake District, for generations, was filmed covering at least 20 vehicles including Mercedes, Jaguars and BMW, in the foul smelling muck.A sign at the entrance to the field reads; 'Polite Notice - DO NOT PARK IN THE FIELD' and another warns; 'SHEEP IN THE FIELD'.Today Mr Hodgson said he was 'no hero', and explained he felt forced to discharge the tanker of slurry over cars parked on his land to protect his livestock and his land.Speaking exclusively to the Daily Mail, he said: 'I'm not proud of what I did. I didn't do it for any particular reason other than the way tourists behave. I just get fed up with the way they treat the Lake District.'I am sick of being abused by people when I ask them not to park on our land.'Mr Hodgson claimed tourists often leave farm gates open, break fences and drop litter across his fields, which border picturesque Rydal Water, a popular beauty spot between Ambleside and Grasmere.

'These motorists have ignored the sign and gone out of their way to park on the field, so fair enough.'Any farmer who has dealt with tourists has dreamed of doing this. I say poor farmer for having to put up with them.'Imagine coming back from a long walk to find your car covered in slurry, horrid. But it is their own fault.'It acts as a good deterrent and is justice, really.'Mr Hodgson, who took over the farm from his father, keeps a flock of over 1,000 Herdwick, Swaledale and Cheviot cross Herdwick sheep, whose wool is used to weave the traditional Lake District Grasmere Tweed.
