My older cousin, Tammy, was also in the same tree. She was hanging on the first big limb, about ten feet below me. Tammy's mother also noticed us at the exact time my dad did. About that time a huge gust of wind came over the tree. I could hear the leaves start to rattle and the tree begin to sway. I remember my dad's voice over the wind yell, "Bart, Hold on tightly." So I did. The next thing I know, I heard Tammy screaming at the top of her lungs, laying flat on the ground. She had fallen out of the tree.
