LOTS of rural spaces where illegal INVADERS are bothering ranchers, etc.
EVERY farm kid/ranch kid I ever knew could shoot very well by age 10 or so.
The invaders can be two footed, four footed or no-footed (snakes). Friends of mine on a farm north of Oil Patch City have four young adults (two boys and two girls) who all learned to shoot as children and carry when working on the farm.
