Tourists don't frequent NS.
And when people from NS travel, they clip tickets, get hookups, sneak past security, bring their own dirtbag food, and sleep on the floor with three other people they met randomly on the internet. I'd wager that the net economic impact of NSers on ski areas and resorts is probably negative.
So really, we're not losing anything but the people who don't know enough not to believe us. And serioudly, look at this ragtag group. It takes about five seconds of honest scrutiny to determine that we're all full of shit.
