Provided you have the right bike(s), bicycling is feasible just about anywhere in north america. I have a cyclocross bike and during the winter I put wide tires on it (700x38), and I can ride even in snow - just ride cautiously (esp at first until you get a feel for how the bike handles), and you can usually get around better than cars in snow
