Ken, Great job. I can only imagine how much effort went into the walk. Well that's not quite true. After a year or so on the PD front lines I have a feel for how much effort went into that. I was quoted in the latest PAN newsletter as saying "If we don't find the cure it will be because some who could have done more, only if it a little bit, did not." Then there are those like you who do more than can be expected. Thank You Jim
