Ballard Nature Center has given us permission, over the years, to place caches on their grounds. To say thanks, in a small way, we are having this event to help keep the trails clean. This CITO event will start at 9:00am and end at 10:00am. There is another activity at the nature center that afternoon, so we are going to make sure the event is not in their way. You may cache all day. The sign in roster will only be available for the one hour. You must sign in to get credit for this event. Ballard Nature Center has given us permission to host this event.
