There could be a big rainbow in the national forests of north Arkansas this summer. Arkansas is under consideration for the annual gathering of the Rainbow Family. Perhaps near Mountain Home. Perhaps around July 4 The group, which dates to the flower power days of the late 1960s, meets annually on Forest Service land, sometimes drawing 10,000 to 25,000 people. It’s all about peace and love and treading lightly on the earth. The group’s unofficial website lists three states, including Arkansas, as being under consideration for this year’s gathering. The U.S. Forest Service doesn’t welcome the gatherings with open arms.
