Check out my yahoo video page for some video I took from Indiana Beach, Michigan's Adventure, and Holiday World. The HW movie is the road trip video series. The first two parts give you a good idea of the other attractions near HW including: Santa's Lodge, Santa Claus Museum, Marengo Cave, and Lincoln Boyhood Memorial. Road Trip part 3 + 4 are exclusively of Holiday World (there is an introduction under the title "Holiday World teaser"). Enjoy and let me know what you think.
Pictures can be seen here as well:
