Yeah I usually hit Afton just because it's closest and has decent variety. I'm an utter noob in the park so it's nice having some smaller boxes too.
How steep are the Granite runs? Like Chicken at Welch or steeper?
Steeper, but like someone said in another post the first section of the runs are steep then they flatten out quite a bit. It is absolutely worth the drive. I also think its a bit better destination than Lutsen just for the night riding, but if you hit Lutsen then Giants the next day...well that would be a better weekend!
Getting an inch of snow is like winning 10 cents in the lottery.
