San Antontio is a wonderful city! You will have a great time! It is very beautiful, the people are friendly, and there are a lot of things to do. There is a river that runs through the city. In downtown there are shops and restaurants along the river. It is called the river walk. It is mostly where the tourists go, but you need to go at least once while you are visiting.

To get an understanding of Mexican and American culture in San Antonio, I would go to the Alamo. The River Walk is also a beautiful place to relax and observe people. These places are a bit touristy, but it's a good start. Ask the staff at the Alamo what other places are historical to Texas culture, as well as American and Mexican culture. San Antonio is a great city! If you're there for 3 months, you should make the 76 mile trip to Austin. (Don't speed) Take in 6th street, SXSW, if it's on-going, Barton Springs, Lake Austin, and Lake Travis especially at sunset! There's a popular restaurant, or at least there used to be, where people would enjoy a beverage and watch the sun set on the lake. Brings back many pleasant memories! Come back and tell me how you did, please! I used to live at 1500 Scenic Blvd. :) Bkk is on the other side of the planet...

It's your first trip abroad, not abroad trip.
