Some parts are really great: appropriately nature-y, secluded, river crossings, etc. But in many other parts you are literally walking along side the highway or traipsing through suburban backyards. If you go in the heat of summer note that there are long stretches without any shade. And none of the maps posted along the way have an ideo locator (did you know that's what the "you are here" arrow is called?), except for the one just off M where some good samaritan taped on a Post-it note to designate the spot.
