Been following right along this thread. Sorry to see you go, now that job is finished. It will be like a good friend moving away. You always say you'll stay in touch, but hardly ever do. The most impressive thing about this story is the volume of down to earth knowledge you have and the matter of fact way you present. You're just a little older than me, and I identify with starting a project you've done before, but now for some strange reason, it takes twice as long and wears you out more! Keep at it, my Friend! If you don't use it, you loose it! Happy camping! David
