Without quoting, in response to some of the comments concerning top to bottom runs being available when they open: PNS being my home hill, I don't think they've ever been open in my 5 years of skiing without having the main top to bottom run, Center Stage, being available whenever they are open.
Hard to compare 400 to 1000 foot vertical, but I would imagine with the increased snowmaking, at least one of the top black or double black runs at TM will be open every day they are open throughout the season.
About opening in November, PNS had their earliest opening last year at this time before Thanksgiving, due to some cold weather, only to be followed up by a dud of a December. If I remember correctly, they had to close some days during the week, but some how kept it open on weekends throughout December until the next solid stretch of snowmaking weather hit in January.
