We're a friendly bunch, so Mariners' gear welcomed - unless it's that dang Cano Dontcha Know! Man, that guy is an Astro killer!
As far as living here on purpose - yep, that's us! We retired to Texas about 18 years ago to a master-planned community north of Houston (The Woodlands). We've loved every minute, with among other things- no state taxes, the diversity, and no winter weather. Did I mention my only grandchild lives 7 minutes away? We agree with the non-native Texans' motto: "We got here just as quick as we could." (A little bit of throw-up came to the back of my throat saying that cuz we were raised to hate all-things-Texas. Sorry, Daddy, changes in latitudes lead to changes in attitudes.)
Hope you have a great time! If you have the time or transportation, you're also just about 90 minutes from the Galveston beach.
