RE: cold weather storage
I am a Native New Yorker, temporarily mis-assigned to Minnesota. I have lived all over the country. In fact, this is the 6th state in which I have had a drivers license.
I don't like having to deal with snow, but I can leave my house and car unlocked and go away for the weekend.
In fact, during the winter months, it's not unusual for people to run into the grocery stores and leave their cars running in the parking lot to stay warm.
