Other than that, there's a parachute club at Cark, gliding at Chipping and of course Blackpool for power aircraft. It might be worth downloading a copy of Skydemon Light - an excellent (and free) piece of navigatoin and flight-planning software, which will show you all the local aviation sites -

If you can make Blackpool, pm me as I have a pal who is based there and may be able to give more info, although I'm sure there will be others on here who can advise.
