I'm pretty happy where I'm at this season. I might have to make a trip to Banff however if I ever actually send in my passport application, only about a 5 hour drive from here.
How gnarly is Banff anyways? All I really know is that it's massive.
It's worth going for the views alone. The scenery is spectacular! Louise has some good steeps on the backside (but rarely has good snow). Sunshine usually has good snow, but is either very flat or very steep due to it's weird layout. Make the trip, you're gonna get laid
