Tired of being holed up inside during the chilly months? Cross country skiing is one of the best forms of aerobic exercise there is. Get out, get your blood pumping and glide through fresh powder as you burn those calories! No need to feel guilty about that post-skiing beer and pizza. Short on time? Pete's Hill is a popular in-town ski area, or venture out into the surrounding mountains with a few friends and make a day of it. For those who don't want to deal with rentals and finding trails, check into Bohart Ranch, an all-inclusive facility with trails for every skill level, even the wee ones.
