This is a little off the D track but the story of Irish "cave drawings" prompted me to respond. I always encourage remodelers to leave little "treasures" in the walls for the next person. Suggestions include: - magazines and newspapers - Daily weather reports - Names ages and dates of those involved - Small bags of coinage Maybe we should be leaving envelopes in the D as we "remodel" them. Problem is that there are not many good hiding places. Just a random thought. NK
