Just got back from San Antonio. Thanks for all the input here!
Must say that I always thought of San Antonio as just another Texas cowtown. Far from it! Could spend a few weeks there seeing all there is to see.
The 5 or 6 interstates which meet there suck. On and off ramps are short and signage leaves much to be desired when you're dragging 40ft of TH behind you. To get to downtown from the KOA, Houston street will take you there with much less stress, lol.
Even got to take the motorcycle for a ride out into the country side. Nice. Love the German influence on the architecture on the farm houses, churches, etc.
