From the Late Night Shots e-mail update: “Washingtonian has posted pictures of last weekend’s 40-something crowd that attended the annual polo classic in horse country. Like oil to water, after the races Huey Lewis was introduced as the encore performance to a crowd that wouldn’t know Marty McFly if he hitched his skateboard to the back of their Buick LeSabre.” So does this mean that the crowd didn’t like Huey Lewis? Do area rich folk really drive Buick LeSabres, or is this some in-joke I’m not getting? What’s “polo”? —-Mark Athitakis
