I know that in certain countries like Japan or South Korea: it’s normal to leave the front door unlocked since the probaility of someone breaking in is low since their crime rate isn’t high. I knew a friend of mine who resides in Korea where they even left the car unlocked with the keys inside, can you do either of those things in America?
Two weeks is an exaggeration… it’s roughly a 40 hour drive. I find 10 hour driving days to be quite reasonable, so 4 days.
But, your point is valid… big country, different places will have different danger levels. Within my own city, there are areas I would feel OK leaving the front door unlocked, and other areas where I absolutely would not.
Reminds me of a joke, A Texan and a Carolinian rancher meet in a bar. The Texan says “Yessir, it takes me two days to drive my pickup truck across my ranch.” The Carolinian says “Yeah I had a truck like that, but I got it fixed.”
