There are so many factors to consider.
Not just what kind of TLM options there are -- that is just the start, and frankly, there are Mass centers all over the place. So you can't just recommend "there's a great traditional chapel over here".
Property taxes, state income tax rate, cost of housing, local culture & people, cost of living, sales tax rate, homeschooling regulations, health of the local economy, etc. Everything needs to be looked at.
And let's not forget survival implications -- proximity to large cities, proximity to California, earthquake vulnerability, proximity to the Atlantic Ocean, etc.
