I have friends that come from upper state NY. They are all fine, stand up people, to a person. They are outnumbered by the city folks when its time to vote. FWIW, same condition exists, at present, in Uruguay. The photos you provided are just great and speak all of the country you are in. Old stone walls were an easy way to clear fields and mark boundries in most places. Further south, but perhaps not, Iris rhyzomes were used as bench marks. For Geo. Washington era surveyors it was the norm and the Iris were known as 'flags'. Here, the blue & white iris retain that name, tho most have no idea why. Check in the spring to see if any are on you, there may be a few and if so they will delineate the original plats. Nothing to do w/grouse, rather a diversionary thot you might file away for post season activity.
