A great way to spend a summer afternoon is riding in an air conditioned car touring the Toccoa River on the Blue Ridge Scenic Railway. 

The vintage train runs a 26 mile track that allows passengers to visit downtown McCaysville, Georgia and Copperhill, Tennessee.  It's a 4 hour trip that only costs about 32 dollars per adult, discounts apply for veterans and seniors.  Check their website at brscenic.com for more details and scheduling.
