Having never been to the Houston show, I'd like to jump in here and suggest you try Paducah first. I see you're located in OK, so it might be close enough to make it a road trip with someone you love to travel with. But, in all fairness, I almost missed out on the Paducah show because of my being a day late and a dollar short everywhere I go. A friend and I just barely made a hotel reservation when I called in last week--they had two open reservations and I was lucky enough to get one. We could drive up and back in one day, but it is a 3 hour drive from our house to Paducah, and parking is a problem when you get there late in the day.
Join AQS, and your tickets are cheaper for both shows. I love the Paducah show, and feel like the Houston show is too big to enjoy. Plus, I am not that crazy about Houston and their horrendous traffic problems. At this point, I don't feel inclined to "go big or stay home".....
