Kelly, thanks for the heads up. Bolivians fought for the right to collect water after a big corporation took over their river, and won.
The thing to do here is to go ahead and collect, as farmers always have done without interference.
(So, it is a right in common law, right?) Then if the state tries to intervene, create a test case and make them prove they own the rain. Maybe ACLU would support it. Maybe E-law would support it.
