A few years back, pre Trump, I led some US rednecks from Niagara to Trenton because they had trouble understanding our maps. One rider in particular was wetting his pants about riding through cities. (They couldn't carry). That guy figured we could go north to Barrie and head east from there, on Goldwings.
I hope I never become that paranoid.
In some little towns people don't lock their doors, leave keys in vehicles. I'm more cautious.
A friend used to leave his cottage unlocked with a notepad on the table. If you dropped in while they were away you left a note, "Thanks for the beer". Now the place is full security, alarms and cameras.
How safe does a safe room have to be if they're out to get you? Common wall construction barely slows down a bullet.
With a typical city lot, a property line breech might give you three seconds warning before someone's at your door. Three seconds later the typical door is kicked in.
To work, safe room drills are needed and you have to live edgy. Unfortunately life is heading that way.
