List users by meta_key and meta_value

What about putting the city/regions/whatever into an array you can loop through? Something like this:

$cities = array( 'Richmond', 'Chicago', 'New York' );
foreach ( $cities as $city ) { ?>

    <h2><?php echo $city; ?></h2>
    <ul><?php
    foreach ( get_users_by_meta_data( 'school_division', $city ) as $user ) { ?>
        <li><?php echo $user->first_name; ?> <?php echo $user->last_name; ?></li>  
    <?php } ?>
    </ul><?php
}
