I'd just like to warn people about wooden sledges. These may look 'authentic' and rather twee but can in fact be very dangerous, the potential for becoming tangled amongst the runners and breaking bones is undeniable, I've seen a couple of nasty accidents, once on the golf course at Mellor (great slope incidentally) and another time in Debdale Park.
Toymaster or Hollins both sell excellent quality plastic sledges at very reasonable prices when snow does fall. These sledges can handle some serious powder carving, whether sat down (weak) or stood up (sweet).
Must recommend the hill opposite the George pub (before the bridge leading into Compstall), absolute belter.
Take care if you are thinking of sledging in the cold seasons, any budding Meteorologists in Marple know if we are due snow this winter?
