Hi neighbors,   It's with mixed feelings that we leave our beloved Highland Park neighborhood for our exciting adventure of home ownership in Swissvale. We sure will miss running into our wonderful friends and neighbors, the mail carriers, the lush greenery, the pool and the Listserve!   The final stage of moving out culminates with putting out the trash on Sunday night. There will be a couple of steamer trunk/foot lockers, a large collection of clean plastic cat litter buckets (great for supporting impromptu basement shelving, gardening, organizing), wooden bookcase boxes, scrap metal, a pallet, etc.   Please take anything you can use. It will all be piled up on the curb on Callowhill, almost at the corner with Negley.   Thanks for the many kindnesses extended to us through the years.   Best wishes, Jonathan King and Amy P. Kennedy
