Well, the last two nights have shown that you really shouldn’t leave early at AT&T Park, with the Giants getting walk-off heroics from Bengie Molina and Daniel Ortmeier.

(By the way, a little editorial aside here: Another thing you shouldn’t do at AT&T Park is the wave. Do you really want to be like Dodgers fans?)

As Opening Week continues with a visit from the Cardinals, there are several giveaways that will help a proud Giants fan appropriately decorate his or her home. Tonight, get the first in a series of posters (courtesy of AT&T) that replicate the cool “Gamer” street banners adorning the streets near AT&T Park. The first will be Matt Cain: “More arm, less talk.”

What’s neat is that all the posters have that strong orange stripe across the middle, so you could put them up end to end across a wall or two. Now that’s wallpaper.

On Friday night, the first Orange Friday of the season, get that refrigerator essential the magnet schedule. Another fine addition to your kitchen would be a 50th anniversary commemorative mug, which fans supporting Saturday’s CHW Food Drive to benefit the San Francisco Food Bank will receive in exchange for a donation of nonperishable food items or $5.
