May events: Mother’s Day hikes, L.A. River events, plus a new P-22 mural

Moms who are wild at heart or don’t want to miss their 10,000 steps might crave a Mother’s Day hike. Think about a picnic along a scenic hiking trail that’s easy for the whole family. It’s a great way to spend outdoors time with Mom — and a good last-minute option if you’re stumped on what to do.
