Bay Area Bike Share Expansion? leaflet mapbox js

The map shows the initial San Francisco Bay Area Bike Share stations with blue circles and more recent stations as of 2/28/2014 with map markers. The most recent dataset has not just the city so explore the peninsula!

If this were for a paying person I'd probably try and make the layer selector a little more customized. But this will do for now w/ some pretty vanilla leaflet.js and a custom basemap easily generated on the Mapbox site.

<meta charset=utf-8 />
<title>BABS stations</title>

var begin = L.geoJson(start,{
  pointToLayer:function(feature, latlng){
      return L.circleMarker(latlng,{
        radius:9,
        fillColor: "orange",
        fillOpacity:.7
      })
  }
}),
end = L.geoJson(end);

var both = [end,begin];

var overMaps = {
  "Starting":begin,
  "Recent":end,
}

var mytile = L.tileLayer('https://{s}.tiles.mapbox.com/v3/mpmckenna8.i60p2il1/{z}/{x}/{y}.png', {
    attribution: '<a href="https://www.mapbox.com/about/maps/" target="_blank">Terms &amp; Feedback</a>'
});

var map = L.map('map', {
  center:[37.7899, -122.4168],
  zoom:13,
  layers:[mytile,end,begin]
})

L.control.layers("",overMaps).addTo(map);
