I lived in Centex for 16 years, from Waco to New Braunfels in 4-5 different cities, and this is spot on.
I spent the last three years in Leander, TX, in a brand new neighborhood where all of my neighbors were either from CA, the Midwest, or the East Coast. They all seemed to love it, while I was burned out by all of the people. The transplants started flooding in around 2015 and caused all of the good (spicy) mom-and-pop Mexican food places to either change their menus to more bland, or close for the first time since I'd lived there. I saw french fries and chicken tenders on tex mex restaurant menus for the first time ever. I guess the new people were requesting that stuff. I was also tired of the heat and hunting leases becoming unaffordable. When a job opened up here in CO, I jumped on it; however, CO has its own issues, lol. I did sleep with all the windows open last night at 25 degs. Love the weather!
I would move back but only near the border where the food and BBQ is better. However even that's changing rapidly due to transplants (white people lol).
