I wish you good luck...and weather. I hope you are not one of those suckers (like me) that bought an Otis Warranty on the weather. On the day he announced that Winter was over it was 82F...Valentines Day.

So.....my friend and his wife from So Dakota decided to escape the cold and come down here for a visit, and all they got in Texas was cold wind, rain, ice and snow this week. They left to go back to a warmer place in So Dakota on Thursday....and immediately the sun came out and our weather turned gorgeous again. It just isn't right!
Anyhow, I wish you good weather in McAllen...and if you were one of the suckers that bought an Otis Warranty, request a refund. I did. Otis says each refund request will be processed by a committee of his Army Squirrels that have been "Bureaucrat Trained"........so I am not holding my breath.
Regards & enjoy your trip!
