We had a very nice riverside site at Elkmont. The weather was wonderful, it couldn't be any more pleasant - about 10 degrees less than the lower elevations and much less humid.
The dance of the Fireflies was extraordinary and truly majestic. It wasn't 'synchronistic' in the manner that I thought it was be - blinking at the same second at the same time, but they where moving in waves all at the same time, as if to some beautiful music. It really was a site to behold and if you ever have an opportunity to see it, you should do so. Thank you everyone for the bday wishes and for a wonderful bday!
