Reader John Heinsen shares some pictures of Saturday's guided hike of Rubio Canyon sponsored by the Arroyos & Foothills Conservancy. Sean Howell subbed for Paul Ayers as hike leader, and John said he came back inspired. There are hikes scheduled for the next two Saturdays led by historian and Altadenablog columnist Michele Zack -- to RSVP, e-mail Sean Howell at seanhowell@arroyosfoothills.org.
