They don't call them the Great Smoky Mountains for nothing.
An Associated Press analysis of federal court data shows that of the more than 27,700 citations issued to people caught with marijuana on federal property since 2009, at least 724 of the tickets were issued at Great Smoky Mountains National Park in Tennessee and North Carolina. Among national parks, that figure trails only Yosemite's 939.
The number of citations issued is small compared to the hundreds of millions of visitors to national parks, forests and monuments each year.
But it nevertheless illustrates one of the many issues Washington, Colorado and other states that want to regulate marijuana face in complying with last month's Justice Department memo that calls on them to keep pot from being used, possessed or grown on federal land.
Here's a look at the top national parks, recreation areas and monuments for marijuana busts from Jan. 1, 2009, to July 31, 2013, according to data provided by the U.S. Courts Central Violations Bureau.
