Something caught my eye in one of your posts about Brady, Pat. You mentioned that when he gets to this certain point on the street, ..."he looks up at the telepone wires and runs". It reminded me of where I used to live. When I would walk my dogs, there was a particular spot where the telephone wires had a humming sound. Once I passed that spot, it was gone. I never knew what it was, but I definately could hear it. This pole, in your neighborhood may not be quite loud enough for you to detect, but maybe Brady is hearing it. Especially if he was not previously hearing it, then suddently it starts as you approach that area. Maybe next time you are there, try to listen closly. Now that you are aware of this, you may be able to pick it up. Or if you do go with a friend, maybe they can hear it. The pole may even be farther up the street and that is where he is just beginning to pick up the sound. You may have to walk farther up, by yourself to actually hear it.
