if you're out Cambridgeshire/Befordshire area Sunday 15th July there's the Kimbolton Country Fayre, a proper modern English country fayre with car show nicely blended in that has loads for non-car enthusiasts and a few cars amoung the trees for the enthusiast, up to 900 cars discretely laid out in the grounds of the school

you can also experience a few of the cars properly with 10 mile passenger rides on some lovely driving roads for a fixed charity donation

the show is stacked out with great stuff plus a fly past by one of the only two airworthy Lancaster bombers always a fantastic experience
