If you ever plan to visit South Dakota, be sure to visit the Dakotagaph web site before you leave. This is the web site of Chad Coppess who has been the senior photographer for the South Dakota Department of Tourism since 1993. His web site describes the best time of year to shoot different subject matter and gives you all sorts of useful tips for shooting in South Dakota. Go take a look… I think you’ll be impressed by the depth of his posts.
I met Chad when he took one of my workshops last year.
