You may want to check just before your trip, some sections have been closed. Some rock slides but mostly downed trees from the heavy snows this winter.
I've been end to end several times and it's always a great ride and only 15 miles from my house
Please pull off to look at the mtns. you will need to keep your mind on the road until you pull over at the many overlooks that are easy to get in and out of on the bike.
If the motorhomes and other slow traffic get to you, we have many roads in western NC that are also great to ride without the slow flatlanders "tourons" = tourist / morons as the locals call them
