I asked the same question about parking on this forum earlier this year before attending my first Bama game ever (Houston), and received a lot of great advice. We wound up parking at Central High School on the corner of 15th and 10th Streets. It only cost $10, there were restrooms on site, it seemed relatively secure, and it wasn't all that far to the stadium. I'd HIGHLY recommend it! My wife and I are planning on being there for the game tomorrow as well.
