I can heartily recommend Wickenby. 20 minutes N.E. Lincoln.
Very active and friendly flying club members and staff. Self-fly hire, flying training on GA and microlight, tailwheel conversion, fantastic cafe open 7 days.
Modern, vintage and kit-built aircraft aplenty and occasional 'Unlimited level' aeros in the overhead. Bijou museum of 12 & 626 Lancaster Squadrons.
But I am biased, having spent most of my free time there for the last 5 years!
