Now that the Colorado Legislature has approved "Rocky Mountain High" as the second official state song (joining that ever-hummable ditty "Where the Columbines Grow"), should we upgrade the rest of our slogans and symbols? Starting with the state motto? From Colorado's days as a territory, the Latin phrase Nil Sine Numine has been part of the official seal -- and despite translations that range from "Nothing Without Providence" to "Nothing Without God," it's held on for more than a century. But now it's high time to separate church and state once and for all, which Colorado could do by adopting as its motto one of the last lines in its new state song: "Everybody's High." Legislators should be able to get behind this, since they've already bought into the explanation that John Denver's song was not referring to drugs. As for the old motto, Colorado Springs could be looking for a gently used slogan.
