The movie was filmed in Dyersville, IA, and the baseball field is still there. It attracts all sorts of people who come to check out the diamond. Now they have the chance to stay in the family farmhouse that also rests on this land -- for $2,000 a night(!!).
Frankly, I don't see it. That seems like a lot of money for a nearly 30-year-old attraction in rural Iowa. Then again, I haven't seen the movie.
