The Friends of Lower Bridger Trails hosts its fifth annual Share the Path potluck Thursday at the Bridger Creek Trailhead Pavilion. Organizers will review updated signage installed in June and demonstrate proper passing protocols for Class 1 e-bikes, traditional mountain bikes, horses, and the family walking three abreast with a stroller. Hot dishes welcome; the association provides paper plates and a portable PA system that echoes pleasantly off the new retaining wall. Contact Marge Haskins at 406-555-0147. The pavilion lights stay on until everyone finds their headlamp.
