that sounds very scary!! We went caching in texas a couple of months ago went for a cache that was in the midde of nowhere, well anyways, I looked and looked for it and finally found it in a tree i went to reach for it and noticed that there was something on it, I took a closer look and it was a huge HORNET nest so I calmly turned around and backed up and then ran!!! I guess that no one had hit it in a while, I hope they sprayed it or something!!!
