Today marks one year since a violent tornado tore across the Ohio River valley region, wreaking EF4 damage in Henryville, IN, and killing eleven people there and in New Borden, where an entire family of five lost their lives. My friend and long-time chase partner Bill Oosterbaan and I had no inkling of the tragedy this tornado would cause several miles northeast of where we intercepted it during its formation and intensification near Palmyra. We just knew we had witnessed the birth of a beast. It was a fantastic, high-adrenaline chase, and Bill and I both got some great video to show for it. Here's my retrospective: http://bit.ly/HenryEF4.
