When someone says there's nothing to do in Houston, I'm always curious what they want. I roll my eyes if their complaint has something to do with unchangeable factors (heat, world class beach, lake, or mountains/snow.)
One complaint that I have is most likely in other cities as well: secondary market pricing for concerts. Bigger names should book multiple nights when they're playing a <20K arena in a metro of 7m. I understand not booking NRG for multiple nights but Toyota or other arenas are different. I don't mind spending more than face but damn $300 per ticket for events especially if it appeals to the 40+ crowd.
Not that I spend that much time outside in the summer, but I don't experience any mosquito issues in central Houston. Or maybe I just grew up on the Texas coast where the county pumped deadly insecticides all summer to make it bearable outside. Perhaps I measure today vs that.
