Lake O'Hara in Yoho National Park, in the Canadian Rockies of British Columbia: this night (last fall) the Northern Lights were unusually brilliant, and at midnight I was almost paralyzed with indecision over where to go to photograph them (a wealth of options). I decided to take a chance and spend a few hours hiking in to this lookout over O'Hara, hoping against hope that I would get there before the light show ended. Luckily I made it just in time! No sleep that night, but well worth the groggy day after.
