I know some people see these things as an opportunity; I never could! I could never pack up my family and take them on a trip without knowing what the future was. My kids, who were extremely well rounded and open to new things would have screamed bloody murder if we had taken them out of their environment.
And teachers just can't "get another job" in a different state. You have to meet certification requirements, which means jumping through lots of stupid hoops. It often takes months.
I know I'm very traditional when it comes to this stuff. My feeling is that the dad wanted to do this, so he dragged the family along.
