I am also from a rural area, I've spent the better part of the last two decades driving through farmland on roads with no posted limit to get to anywhere. The legal speed limit on such roads is 45 MPH but for the most part on the flat, straight segments traffic goes 55ish. County Sheriff doesn't care until somewhere in the 60s unless they're looking to pull you over. If you're on a road that goes through a town just barely large enough to have a police department, you can guarantee that the road suddenly gains a posted limit of 35 MPH without changing in any significant way and that there will be strict enforcement which may or may not be biased towards those with non-local tags. The exception is the state of Indiana. I don't know what they put in the water there, but no one in Indiana seems to have noticed that interstate highways are no longer stuck with the double nickel. Of course they also have the most bare minimum 2+2 interstate where one dawdler refusing to pass a semi can tie up traffic for miles on end.
