Joe told me about this thread, your course is looking good. I agree it will feel more like Sand Valley with some trees and maybe a bit more sand and less tall grass...but maybe you want a slightly different look from the existing courses. I would be happy to give this a play test at any point if you want.
I will be adding trees, likely at the end. I’m trying to determine if there’s a way to do them systematically based on what’s actually on the land, taking into account that most of the land is commercial pine trees that have no business staying there.
You can tell fairly well in the Google satellite image the difference between the perfectly planted rows of Red Pines and the randomness of the other trees. Determining among the random trees which is Jack Pine, White Pine, or Oak is probably going to be difficult though.
White Pines tend to stick out as a bigger tree. For reference elsewhere you can see them on the south east side of largest pre-existing sand blowout area in a reverse L shape (see attached image). Those are standing left of the present 3rd green at Sand Valley (the redan hole) with the hole running NE to SW in the blowout area. Looking at my pics from before the course was built, most of the rest of the trees in that blowout area were Jack Pine but I spotted a few Oak too and I can’t really see a way to see them in the satellite photo unfortunately.
