September is here and the season begins to change, but not before one last (hopefully) heat wave. Fall is a beautiful time to visit bluff country (aka the driftless, aka karst country, aka my favorite place on Earth), to witness nature display her colors on our oaks, maples, birches, aspens, catalpas, basswoods, hackberries, and more. Thanks for bearing with me, I love my trees, and I need to exercise my horticutlure degree and its memorization of trees and scientific names!
