Hi there,
I'm off to university next year, and am a bit worried about keeping current with my flying (I've recently got my PPL

). Clearly, I won't be awash with money.
It seems to me that gliding is a far more affordable way to fly, and it's something I've wanted to try for ages. My question is, how appropriate is gliding to keeping my hand as far as general flying goes? (The possibility of becoming a tug pilot is also at the back of my mind).
Any comments would be much appreciated.
Thanks,
Proctor
