Great idea !
Snag is, at local prices that means a garden shed and a 1/0000th share in a 172 for me, and most 'starter home' types !
I'd rather see the place with some useful flying and no hutches / sheds, but it's a thought - maybe that nice Mr.Travolta would drop in & premiere his next film at the Cranleigh cinema - if it's still there.
I still fancy warbird restoration as an ideal use for the 'field, maybe GA maintenance & testing too.
