Yes tailgate before game. Like stated earlier, we are usually a friendly bunch and you wont have trouble finding a spot to hang out and drink. Also, make sure you take a walk down Melrose as well.
After the game, downtown is a must. There is a ton of construction going on because they are redoing all of the stone in the ped mall so it is a little messy but worth it to get down there. Plenty of bars for everyone's taste.
If you are young and dont mind the walk, I would park downtown or stay close to downtown and walk to stadium, grab a 30 of BL, tailgate, walk back downtown after the game. Guess it depends on were you are staying as to were you park.
