Very nice image, I always wanted to go down to Savanna. I used to live near Charles City, Iowa and often made trips to the river but never went south of Bagley WI.
And it is really that scenic! The view along the river is something to see all seasons of the year. You can get a real time/space jolt on summer evenings when you encounter the paddlewheel river boats cruising by! It hearkens ones thoughts to the time of Mark Twain in a quieter,slower age!
