We moved down here because my stepfather was in the army, so we went to Ft. Hood. You don't want to move there. I was so bored. The big thing I missed was the snow. After being here over 25 years, I don't miss it too much. Most of my childhood was growing up in massachusetts, and new hampshire.
In texas, it's very spread out. The distances between the big cities is hours, by driving. And with big cities come big city problems. Of course, there are big city benefits too.
Theathers, museums, sports venues, malls and shopping.
Depending on where you settle, the coast could be an 11 hour drive(from the panhandle).
Most suburbs of the big cities have those two chains.
I worked at both for a few years, then moved on.
It would take a good couple of days to see all the big cities, and then again, to go to el paso, and amarillo, and corpus christi, and beaumont, and brownsville, and midland, and well, you get the idea. I guess you'll have to spring for an air tix to come down and check it out. Southwest does fly out of manchester, nh, so maybe you could fly down that way.
