Much as I feared then. Minimum concession from any developer, unless of course it can be made profitable.
The only way to protect sites like Thorborough is to sell them off in 1-metre wide strips two miles long to members of the public, with 100% agreement before anyone can sell theirs to a developer, indutrialist of quarrying company. Trouble is there are only so many people with the interest, the income and the inclination.
