I think the previous posts by Admin, James and skiadikt sums up the situation pretty well.
The Otten Empire based at Sunday River prior to ASC was in open warfare with it's previous home at Kmart.
Otten's revolution was to create a new Killington in Maine. Give everything and spend what it takes to make people consider SR instead of K. So let's expends the terrain like crazy, make snow like there's no tomorrow and try to take the ski area open until June, a big grooming felt. All these massive improvements were done in a short period of time in the late 80s/early 90s.
Now SR could be seen as an alternative to K. K had Outer Limits, SR had White Heat, skiing into June, etc. This was a one to one battle that was going to spread out. Otten moved in Kmart's backyard by buying Sugarbush and making some (sic) improvement :roll: . Expensive improvements that in some cases not an improvement and more a mistake and a waste of serious money (see lifts at SB North changes). Kmart moved in Maine with it's purchase of Sugarloaf.
So you have two mini-empire buying ski areas in the New England in it's desire to get the biggest share of the New England market. Empire and ski areas expensions, warfare financed with debt. Les Otten empire eventually gobbled up Kmart empire with all it's debt.
There was a winner and a new ASC was born. One ski area empire which was heavy concentrated in New England with a heavy debt load due to purchases, improvement, etc. ASC was now a big player. It wanted to diversify across North America like Intrawest (another big player). It started investing out West. Then one bad Winter where most Eastern areas suffered and ASC started hurting. The rest is history.
Not sure of the accuracy in the timing these events, but that what I recall.
