About Me

Favorite Quote: "Life isn't about finding yourself. Life is about creating yourself."  - George Bernard Shaw

I've trained my chickens to come to me when I clap my hands three times.

I love the sound of snow crunching beneath my feet. On the coldest, snowiest winter days, I take long walks.
