I used to live about 10minutes from St. Joe, its a nice area, but it is real close to Benton Harbor. there are a lot of campgrounds between Saugatuck & Holland, but just keep in mind the closer you get to Saugatuck the women get tougher and then men get prettier... (where's the rainbow smiley when ya need it

)
actually the whole coast except Pullman has some pretty nice areas, all depends on what you are wanting.
