Where we live, we do get milk delivered from a local farm that doesn't use hormones or anything, and it's the same cost as from the store, but I was amazed to come across such a thing. They certainly didn't have that where I grew up in Los Angeles!
Also what I've heard is good here, is we have local farmer's markets on the weekends. That's on my to-do list. I'd like to get fresh food and support the local growers. Maybe we can eventually make language a complete impediment to understanding. -Hobbes
