Pat was one of my best friends-we'd email several times a day, and regularly bounced ideas off each other. He was a retired DoD fire chief for the Pensacola NAS, and he and I both had a common background working with military requirements. Pat had become very heavy, and had circulation problems. As I understand it, he died from heart failure. His neighbor hadn't seen him one morning, and called for a PD wellness check. Apparently, he had died at night. I later heard that someone in Pensacola had bought his trailer.
RIP, Pat!
