We got ours from A-1 Soils in near Miramar. I think it was like $20 for 1/2 yard. http://www.yelp.com/biz/a-1-soils-hanson-aggregates-san-diego
We got washed coarse sand.
Thank you.Go to any places like RCP Block and sand and they will have river sand. If you can get a yard it will be wayy cheaper than buying bags of sand. Annd they will deliver. I think last time I bought five yards of sand for my horse corral it was about a hundred bucks I split the cost with a couple of friends they bought fifteen yards.
Concrete mix sand I believe is the best because it has small and large sized particles it wont compact like Decomposed granite. San Diego has lots of rivers.... Belive it or not. San Diego River bed goes all the way from the ocean to El Capitan you can find river sand all along the way if you are willing to dig it yourself. But the deal is the rock and sand suppliers actually sterilize it and wash it before selling it. So it doesnt introduce weeds to your yard if you are using it as sand.

1 cu/ yd = 160sqft @ 2" depth
1 sack = 8sqft @ 1" depth
BTW I have Decomposed Granite in my coops and it does pack down but they still can dig dust bath holes in it.... LOL.
