I love San Francisco. It is lovely beyond belief. It has great weather, food, and scenery. You can't go wrong.
I despise Houston. It is a sprawling mess without any character whatsoever. It seems to have been thrown together without any plan for traffic or architecture. Driving there is a complete nightmare. The homes look like McMansions.
ETA- I had to add how much I loved Salzburg. It was a small beautiful town. Austrian food is nothing to get excited about but everything else makes up for it. The Alps are not far away and their parks are lovely.
