The Pittsburgh Post-Gazette reported that a bicyclist was assaulted along the Great Allegheny Passage in Whitaker, Pa., yesterday, and managed to defend herself, along with the help of other bicyclists who stopped to intervene. We're absolutely horrified at this account, and extend our care and concern for her as she recovers. We are thankful for the other bicyclists who came to her defense and chased off the assailant, and for the quick response of the five police departments who pursued him. The GAP is a well-traveled trail, beloved by local residents and used by families, commuters, tourists, and those out for exercise in a beautiful setting. This assault violated the decorum and camaraderie established over decades by trail travelers and volunteers, and interrupted the peace and joy that hundreds of thousands of people experience while on it. We want everyone to feel safe and welcome while enjoying the GAP, and this incident is a reminder that users should remain alert while traveling and aware of their surroundings.
