I have always said that September is the most underrated month in the Lakes Region in New Hampshire. The water is still in the 70's, the sun is strong during the day and, best of all, no one is out on the lake! I have been having a blast up on Merrymeeting offering private lessons to individuals, groups, and families as well as doing a lot of stand up paddling. I found the below article on WMUR this week...it is good to see other people having some fun as well!

Enjoy the fall!
