Dear Everybody. Please excuse the empty post which may show up as a result of a keyboard with a mind of its own and my late afternoon tremor. I only wanted to say that the posts for the last day or so are the reason I joined and remain on the list. I understand that others have other needs which are more ethereal. I, for one, am a meat and potatoes kind of guy when it comes to PD. Happy weekend to all and sundry and especially to those who have taken a break from the stem cell and gun control arguments. Paul H. Lauer
