I can't speak to the other places, but I lived in Houston for 13 years. Not much biking spaces for a longish ride (20 miles or so). Getting out of town for biking isn't easy given the constant traffic gridlock, which these days is almost 24 hours a day. You'll spend a good deal of your day in a car navigating 20+ lanes. Instead of building a rail system they just add more lanes. Biking isn't 12 months a year unless you can tolerate 97 F deg with 95% humidity. Summer in Houston is like winter in N. MN--you don't want to be out much. Houston is a place to live fairly cheaply and make a decent salary while planning your escape. It's not surprising that Texas ranks only 39th in happiness among the states.
