Hi Al,
Dont know what part of kent you are from, but while on the subject of Scout camps, I use Buckmore park in Chatham for running survival courses for the scouts.
This site is very quiet especially in the winter months cheap rates £2.20 per night and very easy to lose yourself in its many acres of woodland.
Their phone number is 01634-672237.
If you fancy poping over when the next course is running gis a ring on 07866-262769, and I will give you the directions.
Good luck,
Steve Harris.
