Couldn't agree more. Would add the restrooms are tolerable if there hasn't been a backup on the floor thru the drains that day. I also do my best to avoid walking under any areas with concrete overhangs.
Other than the supposed 'historical' value (where again nothing signifigant has ever happened here) the place is a complete dump. If you go when the ivy is dead then it looks even worse.
You can't park within 5 miles of the thing and if you aren't the typical city-goer you have no clue how to get on the right el to go there.
On a lighter note, having been to many stadiums that you can argue older or newer is better or whatever, the best food bar none HAS to be the garlic fries at Pac Bell. Plus for such a crappy area of town the stadium is quite nice.
