Of course, I'm thinking about all this with an eye toward an eventual country homestead, but I was surprised to run across a family who're homesteading pretty successfully on their city lot in Pasadena. Pretty neat, though most of the detailed article links don't work. I get the feeling they've been through a recent redesign and expansion and got ahead of themselves.
Also, I give you a link I can't remember where I found: Puppy vs. Kitty. Enjoy the cuteness. (And Kitty's utter unwillingness to give up. For very long.)
