Well, not all news is good, I suppose.
According to Philly.com, the Great Smoky Mountains National Park is second only to Yosemite in number of marijuana busts cited since 2009.
From The Associated Press article:
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.
