Just this past week, I noticed two large Shortleaf Pines in a Green Acres area in a suburbia setting, a good 13 miles east of Atsion Lake. It was the large plate-like bark that made me believe it was a shortleaf. I got confirmation that it was. I forgot that this pine has small holes in its bark called 'resin pockets' so I was not looking for those. One was 80' in circumference, and the one pictured was 86".
