smooth talker GT I agree . AJTJ , I have followed your work for a number of years and like you and JIMQ for insight . I lurk and dont offer much insight as my insight is actually a melding of all the thoughts presented here and at other forums . It has served me well to do that . btw Gt keep that cold air up there for a while longer. I have about 6 more weeks of outdoor work I need to complete .
