Polygons with multiple popups open Fav DC spots

Here's a little map of my favorite two tourist spots I hit up on my recent trip (April 2014) to Washington DC. The two places highlighted are the National Botanical Garden and the Thomas Jefferson Building Library of Congress.

I wanted to get multiple popups being open at the same time to work with the typical map loading method but failed. Maybe I have to use stuff like that as is if I do the L.mapbox.map thing???

Oh well if you have a day free in DC and haven't checked out these two free destinations I highly recommend them.

Plus if you know how to make the mapbox.js api to work with multiple popups as I confusedly described above let me know.

                        //        this.closePopup();  // just comment this
                        this._popup = popup;

return this.addLayer(popup).fire('popupopen', {

var geojson = L.geoJson(data, {

          return {color:"red"}
        }
        else{
          return {color:"purple"}

}
      },
      closeOnClick:false
    });

var map = L.map('map').addLayer(mytile)
    .setView([38.889, -77.0170], 15);
  geojson.addTo(map);
});

}
initialize();
