With sections of Yellowstone National Park just opening or still closed because of heavy snowpack in May, it's no surprise visitation has been down this year when compared to the record year of 2010.

In fact, it's a little surprising that visitation wasn't down more last month, when visitation was 218,317, down 12.8 percent from May 2010 levels, when the weather was better (though still not great) and main roads and entrances weren't closed or curtailed because of weather conditions.
