A group of us are heading out to Colorado in August. One of the couples in our group, doesn't have a 4wd. They are looking for some where to rent a jeep. We will be around the Great Sand Dunes National Park. We were planning on camping on Medano pass the first night, and approaching from the east. Our best option would be on the east side, but I understand the choices may be limited. An internet search has turned up very little. Any help you could give would be appreciated. THANKS!
