I grew up in Brighton, on Kensington road which climbs the highest hill in Livingston county, where the GM proving grounds sit. Half way up the hill and directly across the road from my FILs property is a very large gas well that was put in back in the early eighties.. That well was a large find, the guy who’s property it sits on is very well paid each month, so I can’t believe it is only getting enough gas to compare to what you just mentioned. Rumors were floated about how much gas they found there, but I remember it was enough to put in a “sweetener plant” for it, whatever that is.
