Just Jane our second Lancaster is not so far if you want to add to the overnight stay. Also since mid last year the Mosquito HJ711 is at this location. This also has a good collection of the ground support vehicles for those of you that like heavy machinery.

This is quite large and so can take a good number of people. It does not have covered parking. Not many do in this area from memory.
