San Antonio is very touristy and I have to admit that I like Austin better.
First, we went to the Museum fof Texas History. Since the 1830s there have been a lot of Germans immigrating to the US and starting a new life in Texas. Mostly, they were given land for free and did not have to pay taxes for the first couple of years. Texas wanted to create a state of its own, build up an army and have its land settled, and the Germans wanted to escape hunger and poverty in Germany, create a new community in a better environment, promising a healthy climate, good farming conditions and a lot of fellow Germans.
What I didn't know was, that there were also alot of other nationalities who came to settle in Texas over time. Texas thus pretty much represents a concentrated image of the American melting pot.
After that we went to a Mexican market. I honestly expected something authentic. Real Mexican culture, I guess, whatever that might be. What we got was again the tourist-version of a Mexican market. Every souvenir shop had the same things. Brightly colored dishes and figurines, cheap jewelry and decorations. Very weird. :) Finally, we went to the Alamo. There, the Texans faught for their independence in 1836, won, and since then Texas has been independent from Mexico.
