JC and myself are looking to go to Market Rasen in Lincolnshire on the 19th September leading up to the Lincoln Show. It is a Temporary Holiday Site and you must be a member of the Camping & Caravan Club. It has easy access being central and no need to pre book just be a member. It is listed in the Camping & Caravan monthly Magazine.
Hope this is of some use to anyone.
Best wishes Tony & Jan Charity
