I was talking abut Ellsworth.
If you're gonna build a refinery, it's good to have something to refine.
You have to get pretty far west before you see a well in SD.
Most of 'em are further west in WY.
And there's enough coal methane under the Powder River Basin in SE MT to run this country for a hundred years....if the enviros and their bought and paid for judiciary would let us go get it.
Shallow wells whose only byproduct is mineral water. The cows love it!
