People are always posting about deforestation. Do you realize that there are now much more than the 217 million that were planted back in the 30's. A one hundred mile wide strip of the USA was planted from North Dakota to Texas. My family owns land in this strip. Over Thanksgiving, I was looking at old ariel photos that were taken back in 1950 and comparing to the present. These forests have doubled in size since then. New trees have sprouted all around the old ones. You can see it in the photos.

Here are some pictures that I took this month while hunting.
Most of these trees were not there prior to 1930.
