 Yeah, almost 20 years, George. For part of that time, I left the sort of freelance and I became their aerospace consultant for a few years. But all in all, it was about 20 years. Yeah, they were great years for me. I really, really enjoyed that beat. Went to some fantastic places, learned some incredible things. Yeah, it was a very good, good time. What were your favorite topics that you handled for them?
