OH I agree with you tuna, its a pretty dangerious place for a Pats fan. Used to be a non family place for us to, but we were just what they used to call a "clown team". So they threw beer or said things but didnt get violent alot.
For a Pats fan, I would think to be in a pack and a hotel close by.
But sence Brees they dont mind us anymore. Most Charger fans are underground Brees fans and wish he never left, so wearing the 9 jersey will get you a long way in that stadium. They loved Brees so as long as your willing to listen to the Rivers history, then how much they love Brees and wish he never left, your fine.
You as a AFC rival, successful champions, and wearing #12, with all illegals, as you mentioned, and they have some gangs there, it can be dangerous. The stadium has some dark places, dumpy, and they do hang out outside the bathrooms and in the parking lot.
I do not usually go to stadiums like the chargers unless Im front row. Its a good thing to pass on to other Pats fans as you said, and dont bring family there. Buy high profile seats , come late, and leave early or very late, or have a cab waiting lol.
We usually sit in the front row in these places so cops can see something happening. dear lord I still hate the new Nike uniforms
