 It appears that we've got a local or someone who's unhappy with some of the new trails that are getting put in. We found some grease on some of the rocks. There have been some notes left out. We'd just like to have it resolved and safe, and we'd like to just work together so we can all enjoy the park. Spokane police say it has a police report and is investigating the situation. Spokane Parks and Recreation say they are working with the police as well. Amon says he's disappointed to see the trails he works to maintain be treated so poorly.
