I'm really surprised that Nakiska, the closest hill to Calgary, hasn't jumped on this bandwagon. As far as I can tell, the resort sits idle all summer - there's no hiking access or biking trails there, despite it being located in a high traffic summer activity area. Calgary is a big city with a huge MTB population, but the nearest lift accessed riding is three hours away at either Fernie or Kicking Horse. The Banff hills have summer gondola access and Sunshine's gets to some great hiking, and Lake Louise is busier in the summer than the winter - but RCR seems content to let Nakiska sit empty for months at a time. Maybe they need a few more bad snow years to convince them.
