Before heading out on the Pre-ICS field trip “Giant caves of Northern Mexico” I had a couple of days to spend in San Antonio. I visited the beautiful riverwalk, toured the historic remains of the Almo and viewed the entire city from the top of the Tower of the Americas. The riverwalk was especially nice- even in the heat of the day it seemed quite a bit cooler down in the shade alongside the water, making it a great place to stroll along site seeing.
