The management of Houston Hobby Airport is to be commended for prohibiting parking by tow trucks that are towing a vehicle. Our airport is plagued with that problem---tow trucks park in the arrival and departure lanes all the time. And of course they just sit there for hours at a time. No one ever gets ito or out of the towed vehicle. Why do those drivers not park in the parking garage, with everyone else? There's a huge section of the garage reserved just for tow trucks towing a vehicle. I'm blowing off enough steam to power my abacus for a month!
