Teaching in Dallas

I'm off to Dallas to teach Inspiration from the Garden and Laughing Leaves with a lecture and demo on Machine Quilting. I haven't been to Dallas in 30 years, do you think it has changed much? I know it will be hotter there, I remember that much. It has really cooled off here in the last two days and is raining this morning, residuals from the hurricane down south we've been told. I hope my flight takes off on time!!
