I have lived in San Antonio for the past 2 years as an international student studying at UTSA. Never in my life, I have heard of San Antonio, Alamo, or even riverwalk before I moved to San Antonio, later I heard lot of great things about the Riverwalk and caves of San Antonio when I was researching. Personally, I doubt it, I agree it looks great in pictures, but I don't even know why people like it, the water is super dirty, the only thing which makes it look good are the lighting decoration on the trees. Though the history of San Antonio is very fascinating, and the battle of alamo etc..Its a very quiet and boring place tbh :D
