Newenglandskihistory.com shows some interesting data for skier visits. I would have never guessed Attitash was 3/4 for NH in terms of skier visits throughout the 90s and early 2000s. Wildcat had better numbers than Cannon until 2010-2011. Then just fell off a cliff. I don't know all my pass/industry history but it has never recovered.
