Come to my church.
I have several friends I keep up with in Tampa Bay and southern California who are also that tall, so I know it isn’t just north Texas.
When I last went back to where I grew up (Tulsa) there were a lot.
There are a fair amount of former models in some of my activities so it is possible that this skews my social group.
I am only five eight. Used to be five nine before my discs compressed.
I’m 6’1” I would notice if suddenly there were a lot of females as tall as me, or towering over me.
