Join the Arroyos & Foothills Conservancy and local trails expert Paul Ayers for a hike of a new trail loop in Altadena's Rubio Canyon at 9 a.m. on Saturday, April 28. The trail, restored by Ayers and his volunteer crew, provides a good view of the land AFC and its partners preserved in the canyon in 2011. Meet at 1101 E. Loma Alta Drive, just east of Camp Huntington Road.
