This is my theory too.
I've never understood the "convert the heathens" approach, because if people are happy in the park, that makes me happier in the BC and pow because there are less people using a limited resource.
Do I think that I'm having more fun? Sure. But that doesn't mean that I need to rub that in their faces. The shit-eating grin on my face that accompanies whatever discussions of pow skiing I've done is about as much convincing as people need, and occasionally they recognize that it might be worthwhile to tag along.
