Storage sites run by CLs

I realise that the Club has their own storage facilities for motorhomes and caravans, but there are a lot of other locations out there, that one only finds by chance.

Some are at Cl's and apart from the owner advertising them in the local press, that's it, unless one visits that particular Cl. 

Would it be possible for the club to advertise those Cl's with storage facilities or dedicate a part of this site where one could input a postcode and gain such information?

We store our van on such a Cl, but again only found it by pure chance.
