Or move to somewhere there are good public schools
Where in the US, pray tell, is that?
Actually the public schools in NH are rated as some of the best in the country.
Right down the street from my office in Nashua, NH is The Academy of Science and Design. It is a NH public Charter school. It is a middle & high school. It is free to all NH residents. However, you have to test to get in. Then because of demand, they have a lottery to get in.
It is ranked as the number one high school in the state of NH. Some MA residents PAY to bring their children to this school. The border is about eight miles south.
FYI, they have no major sports teams. No lighted football stadium. One of the only sports teams are track and field.
Busing is provided for students who live in the city of Nashua. If you live outside of Nashua, you need to deliver your children to school. Therefore, every morning on my way to work there is a line of cars making the left turn to get to school.
Let me point out that there is a large percentage of ethnic Asian people in these cars I pass. Especially since Asians only make up about 3% of the NH population.
