Find a local raw milk co-op in your town, or start one like I did. If you live near Miami, FL check out MyHealthyFoodClub.com
Or find a local farm near you at www.RealMilk.com (site endorsed by Weston A Price Foundation).
If you cannot find any fresh raw milk from grassfed pastured cows (or goats) in your area, you can have great quality raw milk shipped to you from a variety of farms around the country.
Here is the farm I've used for years: Miller's Organic Farm. (their phone # is on the full product list PDF)
