We started at Jain Lane west of 183 as it is not finished to the south yet. It is concrete and there are some elevated sections. For it's location it does seem to get away into the open for the most part. Almost completely flat except for a few ups and downs. We biked north past the spur to the Y (probably the ideal place to park). It apparently goes up to Loyola, and past it if you don't mind dirt since it's not finished.
