Not got a solution, or a substitute, but maybe a 'stop gap'? Stick your head up and ask anyone and everyone if you can go flying with them. They won't be able to give you lessons, and you won't be able to take the controls, but at least you'll be up there. You can practice your mapping, do all your usual pre-flights etc (in tandem with your very safety conscious pilot of course) and maybe have a great time as well. As I said, not an answer, but a way of getting into the air.
Why don't you ask here? I'm sure there'll be loads of friendly souls happy to take you up if you just tell everyone where you fly from and where you can get to. Just so long as they're happy to have a 'friend' come along who they don't require to cost share (too much).
