Actually, Dallas/Ft Worth is where you want to be.
If you are on FR you would prefer Fort Worth to either Austin or Dallas. AS for allergies... we have plenty of allergies and allergists !! Nowhere in the inhabitable part of Texas is allergy-friendly. I moved to Ft. Worth area from Denver eons ago and have never been happier !! Welcome to Texas Ya’all ... and as the sign in Risky’s Bar B Q restaurant says.. Like is too short to live in Dallas County !
Just stay out of the Dallas city limits.
