and a cafe with good food
(at Wellesbourne)
When did you go there? I visited a few weeks ago and the food was nothing short of disgusting. The veg looked like it was prepared the previous day.
The airfield itself is fine, and they do have a little bit of hard parking which would be important (essential) for a proportion of visitors.
As I said, Norwich may be worth a look if one can do a deal with one of the flying clubs. Personally I would happily pay the £50 and park on tarmac.
Duxford should be fine, and the food is edible.
