blue oak acorns or seedlings (Stevens Canyon Rd)

I want to sprout some local acorns, specifically blue oaks (quercus douglasii). I have found a couple local trees but no acorns yet. If you know a tree that is producing or can grab me a pocketful of acorns I would be grateful. The photos show an example of a blue oak, its leaf litter (note the lobed leaves), and acorns that the squirrels already got to. Thanks!
