I tried and failed in 2010.
But summer 2011 in Waterton National Park, Canada, I guarantee I’ll be getting on the Glory Board, the list of those who complete 3 best hikes, ideally in one calendar year: Akamina Ridge | Alderson Carthew | Crypt Lake

Maybe we should attempt 2 in one day Rick. Akamina and AC I think is doable.. What do you say?
