Did you know you can ski at over 13 NH ski resorts at a significant discount? A statewide non-profit organization (called Breathe New Hampshire) sells an item called The Fun Pass. It's one of those discount coupon books, but you'll actually use these coupons. In most cases a youth aged 12 and under (some cases 17 and under) skis free with the purchase of an adult ticket. In addition to the skiing, there are over 100 New England attractions in this book (like Boston Duck Tours, Story Land, sporting events, etc.). It sells for $25 and after you've had one or two ski outings it has paid for itself. You can order it at their website: www.breathenh.org. It's definitely worth it - once you've bought one, you will buy it year after year - especially in this economy.
Have fun on the trails!
