I learned to fly at North Hill as a teenager and have fond memories of flying up and down the ridge at the end of the field at low level.
My most recent (yesterday) way of giving my flying some purpose involved flying down to Devon, picking up my father (ex-PPL) and letting him fly most of the way to Rock in Corwall. He got to fly low level (500ft or so) over Bodmin Moor and got to fly between beautiful puffy clouds in bright sunshine. I then got to put down on a tricky strip in a crosswind, giving me a stimulating challenge. I was a wonderful day, sharing the experience.
We then enjoyed lovely crab sandwiches at the Rock Inn and after departing Rock at 5pm I was back at my home airfield near civilisation by 7:30.
You'll get more from your flying if you challenge yourself and think of ways to make your skill and equipment useful beyond just the act of practising its operation.
