The drive from New Orleans to San Antonio was about 9 hours. Rt10 had some areas of construction that tried to shake every bolt loose in my brain and RV. Neo didn't seem to pleased either with the rough sections of road. Soon it will be a pleasant ride for travelers when the construction is complete.
YES THE ALAMO has a basement (You have to be a fan to understand). The Alamo was originally known as Misión San Antonio de Valero. It was founded in the 18th century as a Roman Catholic mission and fortress compound. Now it is a museum in the Alamo Plaza Historic District. "Remember the Alamo". The battle in 1836 and the documented soldiers that died there fighting for freedom Travis, Bowie,Crockett, and Esparza.
I really loved reading all of the history. They do not allow pictures inside the Alamo structure so take your time while inside. In the courtyard they have live history displays of the games, guns, and everyday life. I learned how to play the dice game that was used in the Pirates of the Caribbean movie (side note - but fun).
Going during the week is highly recommended to avoid the crowd if you want to take your time reading the available displays.
THE RIVER WALK or Paseo del Rio is underneath the busy streets of the city. Its only a short distance from the Alamo.
I started my walk from La Villita (Little Village of San Antonio). It similar to the Riverwalk tucked away in the middle of the city wit shops and restaurants.
You can enter the River walk for La Villita through the Arneson River Theatre. The grassy steps are a beautiful quiet place to stop and meditate before starting the long walk.
I believe that the river has paths and sidewalks for 15 miles which provide access to the museums, the King William Historic District, 300-year-old Spanish missions, hotels, mall, shops, and restaurants.
NIGHT TIME - The place is freakin gorgeous at night. I could not capture the lights in the trees, the boats strobe lights, fountains, and restaurants. You have to see it in person.
