Secret second hobbies
I used to shoot with the Civilian Marksmanship Program in the small bore (.22) competitions.
I'm farsighted and it became tough for me to compete, so I gave it up. I do miss teaching the next generations though.
What started as a hobby has turned into a nice little side gig. I rebuild lock cylinders and can re-pin/re-key them.
I also collect illegal gambling chips and other items from the illegal gambling places that were located in Northern Kentucky.
