IDK if i'd call the increase "massive" traffic in LCC and BCC has always been a thing. Even 10 years ago if the canyon is closed you sit in a huge line of cars and then creep up to the mnt and you lucky if you're skiing by 10am. There is an increase in skiers though, SLC's population has doubled in the last 10 years, definitely some new skiers in there, like you
The bigger issue I see is parking, BBC especially has some huge problems, the lots are just too small. But, what is the solution? Mammoth has a similar issue, very small lots and everyone just lines the road with cars, seems like the future of BCC at least. I definitely noticed an increase in traffic/parking in BCC this year, Ikon pass as solitude is definitely causing some of that, but the brighton millennial pass did the same thing last year.
But, it's hard to complain this year, of course people wanna go skiing in Utah it has snowed 400" so far. Will be interesting to see how the ikon pass plays out next year, these resorts with 5-7 days of skiing might just say fuck it.
