I graduated from the police academy in 1980. Was hired on in 79. My mother gave me a, I think it’s called, a knee board. My dad was a pilot in the Army and he used it to copy frequencies, coordinates, etc. My mom saw my dads and got me one. It helped a lot during my rookie years. Write addresses, lookouts, notes, etc on the paper part. Uses Velcro to attach to your leg. Easy off, easy on. Used for one year, done after that. It was damn nice that first year. After that, you get pretty ingrained with the same repetitive addresses. Had more of a problem keeping up with girlfriends after that. To be honest, doesn’t need to be anything big. I found that the OCGA book that was sold at the ga public training center in Forsyth was pretty informative. 20 bucks. I treasured that. I never trashed one for an update.
