Houston can be hot and humid in the summer, so September or October would be more ideal, but
ANY time would be fine for SOS fans! (Air conditioning must have been invented by a Houstonian!

)
Come visit the city with a heart - overnight in August 2005, Houston city government, private companies, and just plain individuals got into gear and made mass arrangements to welcome, shelter, feed, and support all those thousands of Hurricane Katrina refugees from New Orleans when the federal government couldn't get anything done. With its international oil/NASA/medical reputation, Houston is the embodiment of the Texas independent entrepreneurial spirit, but people often are unaware of its unmatched civic compassion.
So Corinne and Andy, grace us with a visit - you can be sure there will be a mass outpouring of love and affection welcoming you here.
(Plus I'm sure the local SOS fans would be willing to chip in to present you two with a couple of 10-gallon hats and make you honorary Texans! Cheers!)
