I was living in CA and my daughter was 17. she and some friends wanted to go camping around Santa Cruz. I told her she could go but only if she took a firearm. She took it even though it was against the law and her friends laughed at me.
Turns out, some guy that had come to their campground turned out to be a murderer years later.
She never needed to use the gun, but she finally had to admit it was a good idea.
My oldest daughter had her CCW before I did. I’ve been carrying since I left MPDC in 1974, but finally got around to making it legal around 10 years ago.
