If it doesn't rain, you will have lots of options for public parking. Note that most of the parking you see in photos of our stadium is reserved for donor season ticket holders with parking passes.
Of the public lots, G2/G3 tends to be more of a student party lot, but it a great location. G4/G5 is more family-oriented, as is B1/B2. The best tailgates, meaning the ones that are the most fun for visiting fans, tend to be farther away from the stadium. The tailgates close to the stadium tend to be tighter and invitation-only (with some exceptions). If you are parking elsewhere, just come to the north end of the stadium and walk north into the paved lots and you will find plenty of warm welcome.
