There is almost no reason to ski solo in your area. When I ran the Let's Go Colorado events in the Spring we usually had up to 50 turn out from the Denver / High Country areas. Most still ski together on a regular basis. All you need to do is make the connection.
Last season Dobson Park (parking lot) was open most days for free parking (the golf course lot works too). Dobson was posted when closed, and you can't stay the night in the park. Two stops on the bus and you can get on the Cascade lift. Not only have I never seen a line at that lift.....I never saw another person. Everybody stays on the bus and walks through the village
