        var myLocation = DbGeography.FromText("POINT(-117.861328 34.089061)");

        //Order by distance (nearest one is at the top)
        var locations = from location in Db.Locations
                        orderby location.Value.Distance(myLocation)
                        select location;

        //get the nearest 10 hotels
        foreach (var hotelLocation in locations.Take(10)) {

            Console.WriteLine(hotelLocation.Key);
