Well technically true, but you won't be able to drive to Galveston. Not to mention that you might not even make it to Houston. I had my flight cancelled twice already. I was supposed to be back from Guatemala Saturday and I'm still here. No telling when I will be back. I had my second flight for Wednesday cancelled too. From what I heard both Hobby and Bush are closed. The planes looked like sharks in Hobby and Bush was 90% closed.
The "planes looked like sharks" was someone using Photoshop. The airports, ecopark, and the parking garages aren't flooded. 45 is now clear from the Galleria to Galveston. I'm not sure about how 45 is around downtown.
But yes, the airports remain closed, but may be open by Friday.
