Recommendations of Events in the UK

Tomorrow

What events would you recommend going to see.  I am thinking about next year (yes I know but have to plan time off work and book boats) so does not matter if they have happened all ready.  We have been to RIAT (several times), Yeovilton Air Day, Chatsworth
County Show, ELR WWII weekend, NYM WWII weekend and Highclere county show.  So quite a variety.  What would you suggest is a most do anywhere in the UK.  Look forward to hearing all your suggestions and what makes it so good.
