I definitely like walking the riverwalk in San Antonio when the temperature was in the mid 50s to mid 60s. It was great. I wish I did not leave it to the very last moment of our trip. I walked with my two oldest kids while the other 3 had breakfast with their dad. We walked about 2 miles, and on the way back, I flagged down a river taxi. For five dollars each, you can get a ride along the river walk. It was fun and very nice.
