Downtown Houston

A real business district, Houston's Downtown is like a succession of gigantic skyscrapers decorated with American flags. Something a bit unusual: you can go through this area in the usual way (the streets) or via the underground galleries built to spare locals from the painful summer sun. If the city itself does not exactly ooze interest, do not miss the view from the top of the JP Morgan Chase Tower, the tallest tower in Texas.

You can visit discover green, they have events throughout the year there. Parking is tricky, there is metered parking and parking lots that are about $10.
