AIR FORCE ACADEMY, Colo. - The Air Force Academy has set aside an outdoor worship area for Pagans, Wiccans, Druids and other Earth-centered believers, school officials said Monday.
A double circle of stones atop a hill on the campus near Colorado Springs has been designated for the group, which previously met indoors. link
