Winter flying
Evening Roob,
As far as winter gliding is concerned, most clubs do try to fly on every possible day throughout the winter. Lack of thermal activity on flat sites generally means short flights, but good for circuit bashing. For prolonged flights you need to go to a ridge site (Parham, Dunstable, Oop North) or a wave site (Oop north). The other consideration in winter is waterlogged airfields, which can shut some clubs down for weeks at a time.
Anyway, if you're anywhere near Welland GC do drop in
Cheers
