I was planning on taking my son and dad to Cosby campground tomorrow, but heard that they had some rough weather there yesterday. So, I decided to call the campground and ask, and found out that the only loop remaining open is A. Apparently there was a minor twister (although I cannot find a confirmation that it was a tornado) that touched down either in the campground or nearby and did quite a bit of damage. They had to relocate some campers in another section to loop A. I was told that what would normally be a quiet weekend with lots of availability is shaping up to be very busy and crowded. The ranger advised that I call before making the 1.5hr drive tomorrow to confirm how many sites are still available.
