 Good morning, and welcome to Beyond the Gates, a tradition of innovation. We are on Season 3, Episode 4 this morning, and I have with me Dr. Carol Johnson. She is a research civil engineer with the Geotechnical and Structures Laboratory, and we're going to be talking about one-of-a-kind blast technology at ERDC. Good morning, Dr. Johnson. Good morning. How are you this morning? Doing very well, thank you. We got fall in the air. We did. What does fall mean?
