It really depends how you plan to spend your pregame time. We like the Brooks/Library area because we can go get ice cream or attend the pregame band concert on our way to the Valley. The trade off is that we are nowhere near Tiger Walk. If you want to go downtown you may prefer something further west. Or if you just plan to eat and watch TV, it really doesn't matter where you set up.
I am selling my passes for the Brooks lot. Parked there a few times last year. The only complaint about this lot is that it can be hard to get out after a game. The lot is paved, shady, and not far from the library. T-mail me if interested.
