As it turns out today my travels took me over about 40-50 miles of country roads . I had mentioned before this area has an abundance of oaks .It just so happens that in one half mile stretch I observed a red oak with red folage just like the white oak in front of my house .Then two white oaks close together both big bushy yard trees with spreading canopies ,80 footers .One red ,one yellow like a sugar maple .
So much for my theory of soil conditions and coloration .It looks more like just the luck of the draw .
