Well I'm certainly not it. This August will only be eight years.
There was a Lieutenant with the university police here in my area that just retired after 40 years. Came OTJ in 1970, all of his time with the same agency. I think he is 62 or 63, so he could technically have stuck it out a couple more years. Really cool guy.
