Your doctor's assistant can now write you a prescription to walk here in Georgia.

In an unusual collaboration the Georgia Association of Physicians Assistants and Georgia State Parks are trying to promote fitness in the great outdoors.

It's usually five dollars to park your vehicle at Georgia state parks but, with the prescription, the fee will be waived.  The hope is that state park hiking trails will be more appealing than a treadmill or neighborhood sidewalk.

Overall, almost thirty percent of adults in Georgia were considered obese in 2010, according to the Centers for Disease control and Prevention.
