Don't go to the Smoky Mountains expecting clean, mountain air:
A pollution advisory was issued Thursday in Great Smoky Mountains National Park warning visitors of unhealthy levels of ground-level ozone.
...
At the Great Smoky Mountains National Park, ozone concentrations exceeding health standards were recorded overnight Wednesday at two higher elevation monitoring stations and conditions were expected to continue Thursday.
This would mark the third unhealthy day of the 2006 summer ozone season in the Smokies, the country's most visited national park on the Tennessee-North Carolina border.
I like my title, but does ozone=haze?
