var nprTiles = L.mapbox.tileLayer('examples.npr-stations').addTo(map);
var nprGrid = L.mapbox.gridLayer('examples.npr-stations').addTo(map);

// You would usually use gridControl to display a box in the corner with your data,
// but since you want a popup you won't initialize the gridControl.

nprGrid.on('click', function(e) {
    if (! return;
    var popup = L.popup()
