First I wanted to say thank you! Awesome post, and lots of fun to tour the gloabe with your kmz.
I wanted to share that I think you may have the wrong island for the "Largest lake on a fresh water island"
You show North Manitou Island in Michegan, but I think the lake you are referring to is on Manitoulin Island in Canada. I attached the kmz just in case.
Keep it up. I can't wait to see what else get added to the list!.
