Driving to Houston on I-45 can be boring

I decided to drive down to Houston for Microsoft Worldwide Partner Conference 2008 (WPC 2008) and it is around 300 miles from my house. The route is simple. First 114 to west from Trophy Club, then down to Houston on I-45 that is extremly boring and takes around 5 hours with a couple of stops. Just before Houston, I decided to have lunch at an IHOP (International House of Pancakes) and they have one of the best omelettes one can get (Big Steak Omelette)
