Oregon is a big state, and most of the rain harvesters live in rural areas. Many sheriffs and county officials in rural counties will likely not enforce such rules.
Look at New York: when the governor brought back mask mandates, 30 county executives, mostly in the upstate area, said they would not enforce the governor’s decree.
So many folks in Hawaii live off grid.
Solar & wind electric, propane for cooking and hot water, septic tanks, and most important catchment systems for water.
They are not a burden on the lives of those on the county or grid systems.
They should be left alone.
We all hope local law enforcement won’t enforce unconstitutional (anti-constitutional) laws, but some will and some have in Oregon (link below). The last line of defense against these increasingly totalitarian decrees from wannabe despots are local officials. Will they resist? The BIG TYRANT has no power without their army on mini-tyrants to do the dirty work.
And we all know what happened to the murderer (Cuomo)!
