When the Slides are in play, I try to arrive early, just to be sure. Still in the end, all that really matters is where you are when they drop the access ropes.
I was coming solo to Whiteface hoping to enjoy the Slides for a third time. To improve my odds, I contacted the mountain and asked if I could ski with a Mountain Host.
I’d skied with a Mountain Host once before, in December a few years back. I was told at that time that many of the hosts really like skiing with guests. They do seem to enjoy it.
