My whole family will be out of town for three weeks. I plan to turn

Why bother? What is your objective?

I've owned homes for 30 years & never bothered to turn off the gas or
water for short vacancies.

Just because nothing has ever happened in your absence doesn't mean it
never will and it doesn't logically extend to others that your
experience means nothing will happen to them. Plenty of folks have come
home to find a flood and/or extensive damage because a fitting let go or
a supply line ruptured etc.
