POST FALLS – Enough beer cans, old blankets and miscellaneous garbage to fill six trash bags made their way out of a rugged canyon in Q'emiln Riverside Park via climbing ropes Saturday, courtesy of a group of volunteers who have met annually for the past three years to improve climbing areas in the park. "It's a fairly clean area, but there are still some of those people who are going to throw garbage on the ground. That's why we're here," said Ian McKelvey, of North Idaho College's Outdoor Pursuits program.
