My friend and I are taking a trip this June. We're leaving from MN and heading to Pennsylvania for a couple days and then heading down through DC, Mount Vernon, and a couple other stops until we get to North Carolina. We're planning on driving through the mountains and any interesting places we might hear of until we hit Nashville,TN. Finally, after a couple of days in Nashville, we're headed to Louisville and then back home. I was wondering if anyone had any ideas of cheap but somewhat clean motels along the way (hopefully under $70) or any weird or fun attractions that aren't really known, especially in NC. Or if anyone just has some advice for us would be great.Thanks.
