How far to go

Got the new 'updated' Sites directory .The first thing I usually do (as a motorcaravanner) is to go through it (sad I know) and highlight those sites and CL's closet to towns/villages/attractions. However in new book only the large sites have this information . No wonder CL's are closing doiwn at a fast rate - they will if we don't use them and I won';t use them unless I know exactly where they are.
