We spent the majority of our day today walking (and I mean walking) around San Antonio. We put on over 10 miles. The Riverwalk in San Antonio was beautiful and should not be missed if you get to the area. We started our day at the Alamo, walked the riverwalk and saw the lock system, walked around Market Square, walked to the Tower of the Americas and saw the view from 750' in the air, walked to the Rivercenter Mall, then finally had supper there. Not only is this one of the prettiest cities, but it was also very clean. San Antonio is definitely one of the highlights so far of our trip.
