I used to do SAR, I also volunteered on diff missing persons cases and even working to recover lost dogs. I've helped people find their lost loved ones fleshy and furry. I miss having the time and abilities to do so.
You don't have to save people's lives or locate their lost whatever to make a difference. It doesn't take much to give back to our communities. Just being nice and showing gratitude in our day to day goes a long way.
