Bruce,
I hear ya. Tennessee has no state income tax, but a stiff sales tax on just about everything, 8% (food) to 9% (non-food items). Knox county is a quarter of a point higher, but thankfully I live in Loudon county. However, with the lower prices for housing and miniscule property taxes (about 25% of what I was paying in Illinois on a smaller house) we have found this to be a great place to retire.
Approximately 60% of our community is from Michigan, followed by Florida and Illinois. The Florida component confused me at first, but those who migrated north found Florida to be some or all of the following:
1. too hot and humid (doh!)
2. too congested
3. too far from family members still living in the north
All in all, TAN-ah-see is a good place to live. We never considered Oregon because we heard it rains all the time, not unlike Seattle. True?
