Killarney National Park is the oldest national park in Ireland, and a popular tourist destination. In a controversy mimicking similar debates in U.S. parks, Killarney is currently the scene of controversy over a requirement that horse-drawn carts using the park be fitted with a "dung catcher device," referred to in some media reports as "nappies."

Earlier this summer Interior Secretary Ken Salazar designated three weekends as "entrance free" weekends in the National Park System. Anecdotally, the first of those three weekends attracted larger-than-normal turnouts to many parks. Which makes us wonder, do you mind paying entrance fees, or should they be eliminated?
