My wife and I recently found a new (to us anyway) local farm that sells grass fed beef, chickens, eggs, etc.
The great thing about local organic farms is that they're always willing to educate the public about the importance of organic food and grass fed (or free grazed) animals. This particular farm gave us pamphlets talking about just that, and said they would love to give us a tour of the place whenever we wanted (which is always a question I ask them, and you should too).
Where else can you actually learn a little about what exactly it is you're feeding yourselves and your family?
Just try asking your local food store or favorite hamburger joint if they could tell you a little bit about the history of the meat or eggs or produce you are buying. It simply amazes me that no one really seems to care about where the food they eat comes from or the path it took to get there.
If local farms are within driving distance from where you live, then do yourself a favor and take your family on a little road trip. You will be amazed at what you learn, not to mention how much better organic and or free grazed foods taste.
