Looking at glimpses of the audience from the photos posted on Facebook, I am guessing that there were between twenty and thirty people in attendance. But it's really just a guess. It's definitely clear that the audience was very light.
The timing of the event was pretty rough. It was the day after Christmas at a closed ski resort. The weather definitely did not help.
They don't seem to use events as a way to generate excitement for the mountain. They seem to insist that they be money-makers on their own. For example, they are charging $10 per person ($20 for a family of four) for a presentation about owls tonight. I'll pass on that one.
EDIT: They just cancelled the owl event.
So they cancelled the owl event. That means that, during a crucial holiday week for them and the condo owners, NOTHING is going on up at the mountain. Sad, very sad. At least TRY to do something.
