Welcome to Central Texas! I hope your move has been smooth and safe. I don’t think you’ll miss the big city all that much. In addition to proximity to your grandchildren, you are pretty close to Austin, which is one of the greatest small cities in the world of course :). I’m also a transplant from East Texas, and I can tell you I don’t miss the humidity much at all. People here will complain about it being humid, and you can just laugh at them openly (it’s OK).
Also, there is the BBQ! You just moved into the middle BBQ Mecca, which is not a bad place to be.
Anyway, I just joined the site here and noticed your post. I’ve enjoyed looking at your projects, and hope to see some more soon. PM me if you would like any advice on area knowledge.
