No major city in the world is a good place for a ski place, if you mean a good place to ski. Skiing requires snow and a slope, so ski places are more generally located in mountains. However, Seattle is near several major ski areas, including Snoqualmie Pass, Mt Baker, and farther north in Canada, Whistler-Blackcomb Mountain. So if you wanted to sell ski gear, then Seattle might be a place where you can locate a ski shop.
