A 3:30 a.m. Thursday fire of unknown origin destroyed the Happy Trails Lodge at Huxley. Smoke from the blaze was first noticed by Mr. and Mrs. Glen Rogers of Bethany, La. who were guests at the motel. Fire departments from Huxley, Center and Joaquin were called to the scene, but by the time they arrived the 10-unit motel was virtually engulfed in flame. Dave Selvy, owner of the lodge since purchasing it from Doyle Watson, said no one has been able to figure out exactly what caused the fire.
