Thanks for the chart Farm hunter, It gave me a good Idea of how Im going to plant them. I will probably go with 12x12 because like Hotburn76 said, we to use a bush hog so I want enough space to mow around them.

-GR8Rally, I think your winter isnt going to be over for awhile, according from what Ive seen on the weather channel you have over 100" of snow, Holy Crap!! I think know matter what kind of work we have to do we will enjoy the outcome. We have 186 acres of property and about 80 of it is fields that we are going to manage wildlife on.
