Update, now have the second route - thanks to johnlad (has it been checked, is it all legit mate?).
i drove the route 3 weeks ago as part of a group from LRUK forum all was checked and legal then, cant see anything changing so soon,
You may want a re-think on your choice of campsite as the owner is a miserable get, his rules are no bbq's, no noise after 21.00, and basically no enjoying yourself which is a shame as 1 of the lanes is right outside his farm
