Well, if your husband retiring is why we are in this terrible drought, I vote he goes back to work too! haha, just kidding. Research the areas you are planning to visit, maybe the recovery efforts will be concluded prior to your travel dates.
They're predicting 50-60% chance of rain starting this Thursday, thru the weekend (Houston area), so tell your husband to hold off on going back to work. Things may be changing (at least I really hope they are!)
