Jackson Hole, Wyoming is known worldwide as a mecca for skiers and snowboarders because of the stunningly steep and beautiful Grand Tetons. Wyoming is not known as a particularly progressive environmental state but you wouldn't know it from all the bike lanes they've installed.
Go into a sporting goods store and you wouldn't know summer ended because of all the bikes on display. They even sell studded tires to ensure you cut through any ice.
The whole area is covered in bike lanes. Go Jackson and Driggs and go guy on the bike.
