Whitbread - I don't envy you that trip - Michigan to Houston. Fifty years ago - almost to the day - I made a trip to a conference in Houston. Anchorage, AK to Houston, TX. Walking from the plane to the terminal - I thought the plane had made a left turn and we were in HELL.
I had NEVER experienced such heat and humidity. The terminal was no better. It was their brand new International terminal and they were experiencing problems with the air conditioning system.
Galveston was much better and there they have great seafood.
