Why would you give a shit? Do you feel that way about alcohol? Cigarettes? The overwhelming majority of people getting high are discreet and respectful. It's a 100% completely arbitrary distinction with no foundation in reality. This manufactured rage and indignation is so fucking pathetic. Why ANYONE cares what another individual does when it has no bearing whatsoever on them personally is beyond me.
A "giant cloud of marijuana smoke"...what does that even mean? Where's the line between giant cloud and midget cloud?
I'm not saying that ski areas are obligated or even should outright condone pot use, but making this an issue and a line in the sand is fucking dumb. Ski areas have been intertwined with drink and drug culture since their creation.
Oh, and as for these buttoned up family men you're using as an argument construct, those are the guys that solicit me for pot as I walk to the grocery store all winter long. I'm never approached by young people, always by guys in their 40's and 50's whom ostensibly have these families and are spending the money. If the kid is young enough to have no idea what he's smelling, it's a moot point, and if he's old enough to know, it's a teachable moment and nothing that people aren't exposed to in school and elsewhere on a daily basis. If you feel strongly against the use of pot, be a parent and explain why to your kids, and the same goes with alcohol.
In short, the fact that this is a controversy is comical. Especially in an area where there is overwhelming support in favor of the total legalization and de-demonization of pot. But, hey, there's always Utah! In another five years cultural attitudes will have shifted to the point where pot tourism will be a real financial draw and this conversation will be very different.
