JSON.NET and arrays using LINQ

Question

I covered this Parsing JSON question using Json.net and it is close to what I need. Critical difference. I need to parse an array of x, y pairs that form one or more lines per record. Here is an example of my input

{
"displayFieldName" : "FACILITYID", 
"fieldAliases" : {
"FACILITYID" : "Facility Identifier", 
}, 
"geometryType" : "esriGeometryPolyline", 
"spatialReference" : {
  "wkid" : 4326
}, 
"features" : [
{
  "attributes" : {
    "FACILITYID" : "", 
    "OBJECTID" : 1, 
  }, 
  "geometry" : 
  {
    "paths" : 
    [
      [
        [-80.3538239379999, 27.386884271], 
        [-80.3538100319999, 27.3868901900001], 
        [-80.3538157239999, 27.3869008510001]
      ]
    ]
  }
}, 
{
  "attributes" : {
    "FACILITYID" : "", 
    "OBJECTID" : 2, 
  }, 
  "geometry" : 
  {
    "paths" : 
    [
      [
        [-80.3538239379999, 27.386884271], 
        [-80.3538295849999, 27.3868948420001]
      ]
    ]
  }
}
]
}

(Check out http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/WaterTemplate/WaterDistributionNetwork/MapServer/9/query?outFields= * & where = OBJECTID% 3C20 & f = pjson for a full list)

I need to parse arrays of ["features"] ["geometry"] ["paths"] in strings consisting of x, y pairs. This is how I get all the paths (one per record, as in an array of functions):

var allPaths = from p in jsonObject["features"].Children()["geometry"]
               select p["paths"];

, :

foreach (var eachPolylineInPath in allPaths)
{
  IEnumerable<Point> linePoints = from line in eachPolylineInPath.Children()
                                  select new Point(
                                                  (double) line[0],
                                                  (double) line[1],
                                                  double.NaN);
}
