The Mississippi River is a great place for all kinds of recreation and during the summer many people use it for fishing, paddling, or just running their speed boats. Seeing a sail boat with all sails set is not an everyday occurrence and the puffy clouds on the Wisconsin side of the river made for a nice background.
The guy handled his boat actually very well in the evening breeze. The photos were made just below lock and dam #11 in Dubuque, IA and the river is here only about 400 meters wide.
The soaring pelican may explain why I had the long lens on the camera during the little walk with our dog Cooper along the river. Unfortunately this was the only one we had within shooting range. Including part of a cloud was key for this image.
