These are photos of the return trip from the San Antonio bus depot to the McAllen bus depot.
It's a 4-hour drive that I've taken many times; but, lately, I'd rather take the bus than drive it myself. You can read a book, take a nap, do some web browsing, or just zone out. Let somebody else take the wheel.
Although, if there were a McAllen to San Antonio train, I'd rather ride that.
