640 is one square mile 1/2 mile x 1/2 mile is 1/4 of a square mile=160 acres. His math is correct.
I apologize the 160 is correct. I was thinking half a section, that would be a 1/2 x 1 mile. But I stand by my statement that 160 free would be a heck of a deal.
Seams like once we the people give what, at the time, seams like a reasonable inch and "they" take the unreasonable mile we can only get that mile back one inch at a time.
No spelun and grammar is not my specialty. So please don't hurt my sensitive little feelings by teasing me about it.
