Yesterday I posted photos of the Downtown Houston skyline. Today I have photos of what the downtown buildings look like up-close from the downtown streets. One thing I found interesting about walking around downtown there was hardly anone else walking around downtown. That is because most of the downtown buildings are connected by an underground tunnel system, which also has a variety of food and retail shops. So you don’t have the hustle and bustle on the streets like you do in most major city downtowns. This underground system makes sense due to the brutal heat and humidity in Houston. I would describe the tunnels as a skywalk combined with an airport terminal. Even though I sweated like crazy on the streets, it was nice to walk around and take pictures and not have to deal with crowded sidewalks.
