The fire roads and narrow trails of Debs Park in Montecito Heights will be filled on Saturday morning with the hardy runners who signed up for the 4-mile Hill Challenge, which benefits the Audubon Center. The event includes a post-run party and Kiddie 1k. Less strenuous events this weekend include Saturday night gallery openings across Eagle Rock and Highland Park; a street artist show in Lincoln Heights, film screenings and a church rummage sale in Echo Park and a photo exhibit in Boyle Heights. There’s also a community clean up in Mount Washington. More to do in Save the Date.
