The ones we do that I have attended are.
National day. Last time @ Stamford House, Northamptonshire I think.

Cornwall Regional Rally/Show weekend (Very good this one). At Wadebridge usually.

RS Combe @ Castle Combe Racetrack (V Good laugh if you camp out the night beforeon site).

Rallye Day @ Castlecombe (Usually no camping onsite the night before).

Ford Fair @ Silverstone. (Again good camping laugh the night before).

Not sure if we are doing our own Regional show this year. Talk about it though........
