No dangerous drop-offs on the Baldy hike. Just steep climbs.
Joshua tree is cool, but it's far enough from Oxnard I'd probably only go for an overnighter camping.
Surprised I forgot about Getty. I love that place. The biggest mind-blowing bit for me is the impressionists. I'd grown up seeing photos of the paintings, but being close enough to touch them (hands in pockets, kids!), seeing the 3D layering of paint that Van Gogh's hands actually laid down on the canvas, is amazing.
