All in the same area , West of Cambridge.
Bourn (Rural Flying Club) usual stuff and I think there is a Cub available. Nice, small freindly. Hard, lumpy runway.
Bourn
Gliders at
Gransden Lodge
Little Gransden, small farm grass strip, home of Yak UK always intersting things going on
Skyline probably the cheapest hire rates if you join the club. But watch out for away landing fees as there are no crcuits at Little Gransden.
All have good reputations. Ian Austen at Skyline is a particularly good instructor. (Also does aeros in Yaks)
Good luck.
