Moving to Texas (DFW, Llano, Gainesville)

Thinking of moving to Texas (Dallas,Llano, Gainsville)

Cruising the Craigslist housing offerings for 62 and older. I see various cities listed. I'm debating moving there as a 62+ old fart. Subsidized housing already located. I'm PNW raised and have spent a brief time in Lampasas (Vacation) I know the place gets very humid but was very impressed with cost.

Any advice? I'm not looking for political issues, more of living issues, safe spots, places (cities) to avoid.

Or have you lived in the north and come down and what would you do different?
