During his 20 years on the San Diego, CA / Tijuana, Mexico border, Supervisory Border Patrol Agent Randy Williamson participated in almost every activity the Border Patrol has. He was a backcountry Signcutter, a Horse Patrol Supervisor, and an Observer in the first Helicopter Aircrew to be operational in the Border Patrol. He Supervised the Chula Vista Sector All Terrain Vehicle Unit for three years, was a Transportation Check Supervisor and Supervised the Sector Prosecutions Unit for a tour. There wasn't a whole lot he didn't do.
