The one thing I see as an advantage is that it would serve the people living on the east side of Winnipesaukee. It's quite a haul to the areas north of there and even to Gunstock on the west shore. I believe there has been significant growth in the lake area since Moose's closure.
I live about 10 minutes east of Winnipesaukee. There is plenty of skiing within a reasonable drive - from tiny rope tow areas such as Abenaki, Powderhouse Hill, Red Hill, and Bauneg Beg, to the small but well developed King Pine, to midsized areas such as Cranmore, Shawnee Peak, and Gunstock (which isn't really that far at all from the Alton traffic circle), there is already plenty of skiing available. Unless a major expansion was conducted, Moose Mountain wouldn't be in the same league as Cranmore/Shawnee/Gunstock, so it would be competing with the small ropetow areas and King Pine. King Pine is a well oiled machine, so they'd have to figure out a way to differentiate themselves.
I am extremely jealous of you. My goal is to get into the Winni area one of these days. Great lake and great skiing of course.
It really is a neat location - within a half hour or so of Lake Winnipesaukee, Squam Lake, Sebago Lake, Ossipee Lake, etc., and within 10 minutes of the Ossipee Mountains and the southern White Mountains. And no income tax or sales tax
