How it Looks

L.mapquest.key = 'KEY';
var baseLayer = L.mapquest.tileLayer('map');

var map ='map', {
  center: [37.7749, -122.4194],
  layers: baseLayer,
  zoom: 12

  'Map': baseLayer,
  'Hybrid': L.mapquest.tileLayer('hybrid'),
  'Satellite': L.mapquest.tileLayer('satellite'),
  'Light': L.mapquest.tileLayer('light'),
  'Dark': L.mapquest.tileLayer('dark')
