We had a major spider ballooning event today! I saw the first pieces from our house and then, from the top of Pine Mountain where I went to walk the dog more than a mile later, which is about 2 miles and almost exactly across the wind from us. It was at the top that I chased down a "floater" and saw to my surprise that it was a very sticky mass of silk. We ended up finding three "downed" gossamer pieces, but didn't see any spiders. It was very wild.
