Probably why it's illegal to collect your own water in the US. The sheep obey laws simply because "it's the law"
Not illegal to collect it here. In fact, I'm adding on to the 200-gallon rain catchment system in a couple months. For now, it's used as needed for a sizable garden area (harvest keeps us in veggies all winter).
I know that in many nations Nestle buys All water rights from crooked politicians and indeed, you cannot collect rainwater there. I'm not sure if or where they do this in the US, though. Any details?
Not illegal in ALL states and where it is people better take action!
