We started with one cow in 2004. Subhadra and her calf Mahalaxmi. Since then we've learned a lot from our lovely cows. They have us, we do not have them.
My teacher Srila Prabhupada always told me that cows are the harbingers of great prosperity, and therefore putting that to test we designed our economic strategy as not Wall Street but Cow Street. And since then it became a hack of an adventure. Perhaps a book should be in order.
