The walking crowd on your left and right seems to get thicker. A line of fans uncoils off the top step from the MetroLink station. Is that a MILES 12 shirt? They made those? The vendors hawk doughy long-rod pretzels and bottles of drinks that are, indubitably declared, cheaper than inside. You roll down a window to catch a whiff of the snacks. Sure enough, you spot an old family friend, and it reminds you that you get to share this experience with those you care about, even if you didn’t know they’d be there that day. You also see people you don’t know but, really, they’re all friends for the next three hours, and even if you have nothing in common, at this moment you have everything in common, because the only thing that matters is baseball — and the Cardinal carnival awaits inside. (The carnival even has an organist!)
