Isn't digging them out part of the problem?

I might have some of the ludicrous number in Angus. Will send in if I find some.
Unfortunately, it is not the sort of thing you want to photograph.

There's a request for more photographs as evidence if the blight these tracks cause - see news article on JMT website here, where there is also a link to a website where you can upload photos or email them in.

Cheers,
