Hunter is absolutely correct. But if I was going to do 2 weeks and had never done it before I'd probably do the trail along the Skyline drive from I64 north. Then if you still feel friskie and have made that in a week continue up to Harpers Ferry, WV. Trail is pretty mild along the Skyline drive but when it leaves near Front Royal it becaomes a roller coaster till Harpers Ferry.
Grayson Highlands in Virginia is beautiful, and can be completed in less than 2 weeks. Smoky Mountains section is also great.
That depends on ur gear, ur fitness and ur desires. That's akin to asking "I need a car, what do you recommend "
