Nah, I don't think it's hypocritical. Things change. Besides the fact that it is a nonmotivating influence on me, one reason I don't smoke is because I'm a parent and it (was) illegal (also, my lungs suck. And blow. And suck. And blow ... j/k ... no they burn and they are kind of weak).
But what is the difference between this and party buses? They are both legal, and as has been said repeatedly, it is really preferable to having drunks on the mountain.
I have heard stories about Bear Mtn, and other California places, and it does seem quite different than what we see here. If you aren't looking for it, and don't know what it smells like, it isn't really that obvious. I know my kids had no clue about skiing and pot until they were in high school. They know how I feel about both smoking and drinking. I don't hide my drinking from them. I have told them that I don't mind marijuana for adults, but I certainly don't want them drinking or smoking, partly because it's illegal, but mainly because of the health effects on developing brains. We get into the science of it.
I know my kids, and you know your kid, and I am not second guessing that. But I don't think this is a big deal, in the sense of keeping people away. At least it's legal ... they are still doing it in Utah, believe me.
That said, we don't really know how it will affect the landscape. I am not seeing it change much, and frankly, if it would slow the tourons down, I'm all for it. ;-)
