great tour, with a great guide. The downfall was that it was a rainy day and the vehicle restricted our viewsomewhat. The guide worked hard to get us out to see the sites and enjoy the tour. Five stars to our GUIDE. The 4 stars was for weather, which the tour had zero control over. Great city. If you are in Houston, you need to do this tour, just to embrace the city. No traffic, no people on the street. Take the tour to find out why one of the largest cities has no traffic.
