Ive been pouring over the web looking for an aerial map that had all 4 of my fields on my 85 acre piece on it. I had not found any until I found this one. I dont know if its so up to date for everyone else but it sure is for my area! There is unfortnately some shade in the photos but I can even see where I have a section of green clover in a field and then dead grass from gly in the rest. Hope you enjoy and find it up to date for you as well.
