My GGF served under that flag in the 11th Texas Infantry Regiment CSA and I would proudly serve under it as well.
My family has been in Texas since 1852, so I guess that makes me a “real Texan”.
I have you beat by a few years...ancestors settled in Texas in 1830. We lived there until 2005. Finally left due to the heat. Just got tired of two months of 100’s, rest of the time in summer 99’s. Also the property taxes and home owner’s insurance are pretty hefty for retirees.
It was hard to leave Texas, the people there are great but found good people here in the Ozarks of Missouri. We love it here and are not sorry we moved but politics in MO are iffy.
State is pretty evenly divided politically although our county is about 95% conservative. Doubtful the state would ever secede with Kansas City and St. Louis having lots of liberal votes!
