DENVER → OPEN HORIZON / SELF-GUIDED BRANCH
Take your own road through Eastern & Southeast Plains.
Start from Denver / Front Range if that is your natural launch, then let Fort Morgan northeast / Pueblo southeast take over once you are in the region. Compare darkness, roads, camping, facilities and telescope setup before choosing the night.
