The fourth preseason game is generally a pretty "meh" affair for the starters. Many of them will not play a snap, and the ones that do get some snaps, will likely only get a series or two. That means for the roster locks, they get a trip down to San Diego and have to figure out how to entertain themselves in the meantime.
If you are on Twitter I highly recommend giving @49ers a follow as they have all sorts of random interesting things to tweet out before games. They are one of the more interesting Twitter accounts, providing a mix of pictures and video to entertain the Faithful.
They also tweeted out this picture. I'm not sure I can get fired up like they might want with that tweet language, but it's still a pretty cool picture.
