We're lucky to live in a state that is really pretty lenient about raw milk sales—Robbyn at The Back Forty has tons of info on some of the ridiculous regulations that other states have. Anyway, we occasionally pick up raw milk at our awesome local food co-op, Kimberton's, which has pretty much everything in the way of local, organic, and sustainable food. A couple days ago I stopped in and learned that they've got milk from a new dairy that uses nice, re-usable glass bottles. I paid a $2 bottle deposit and picked up a jug—much nicer than the little plastic bottles we used to get.
If you've never had raw milk, I highly recommend giving it a try. It's delicious, and you can search raw milk producers by state at the Weston A. Price Foundation's Real Milk page, on eatwild.com, or on www.localharvest.org.
