Last June I taught a 5 day workshop called, "The Macro World of Madeline Island" at the Madeline Island School of Arts. Located in Lake Superior in Wisconsin. It's an awesome facility where you, learn, eat, and have housing. The island has lots of great opportunities for macro and close-ups.
I will be running this workshop again in June of 2020. They are now open for registrations, and last years filled up pretty quick. Hope to see you there next year. Here is a link to the info. https://tinyurl.com/y2wsjn7a
