I just don't see Loaf and River working against each other, I think they both have something special going for them and work well in conjunction. Just my opinion, but I just don't see that for an Attitash/Wildcat card.
To the consumer, I'd definitely agree. The problem with the two being under common ownership is that Sunday River is a cash cow and Sugarloaf is not. From what I can gather, ASC and Boyne have been worried that capital improvements at Sugarloaf might increase skier visits by detracting from Sunday River's customer base. Before Saddleback emerged as somewhat of a player in Western Maine, this was certainly true. For instance, if Sugarloaf had received some much needed lift upgrades, Sunday River goers might be more inclined to drive the extra hour to Sugarloaf. Certainly, some Boston-area skiers would ski Sugarloaf over Vermont if they made the right improvements, but Sugarloaf has been at a disadvantage because SR dominates the Western Maine market. When I think about it from management's perspective, I can't justify them spending more than 10-15% of their marketing efforts on Sugarloaf assuming resources are scarce.
Boyne has gotten creative with the Brackett Basin expansion trying to tap into a market that Sunday River hasn't already covered. Lift upgrades and things of that nature aren't likely to receive as good an ROI because they'd detract from SR's business. The same could hold true between Wildcat and Attitash. There's no doubt that Wildcat is the better ski area, but the way things currently stand, people are making the choice (in masses) to ski Attitash or Cranmore when they're literally right down the street. If Peak were to run ROI projections at Wildcat, they would likely find that, like Sunday River, making improvements to the "skiers'" resort would likely detract from their (currently) stronger business.
.... I don't really think it's gonna happen, but its an interesting discussion if nothing else.
