This tour was well worth the drive out to the Greenbrier and the $30 per person fee. It was one of the most unique tours I've ever taken!
I wish you could take pictures inside the bunker, but they are not allowed. At least the tour price includes a few postcards to take home with you.
If you are going to the Greenbrier just for the tour, keep in mind that the food there is very expensive. We paid close to $30 for two small sandwiches! You may want to eat elsewhere before or after.
