As for Texas in November the best place for Tennis would be in the Hill Country - Austin, San Antonio - weather still nice ( can start to get chilly) but for the most part you can have lots of days where it can hit well above 70s (20+c). also warm in Corpus Christi region with again lots and lots of Tennis events across the state.
Check out New Braunfels - where Newks is - lots of adult clinics -
Where it gets cold would be North Texas like Dallas and out west in Amarillo, Lubbock....by mid November down right brutal
Excellent detailed info! Im gonna have a hard time choosing between SF and Texas. Maybe ill do both! I really wanna see if i can get there in time for election day, could be quite fun, i guess that these places would be mostly pro Romney, right?
