I have to watch myself more carefully as I develop a form of vertigo, I think, as I have felt very uneasy when exposing myself to heights. I am no spring chicken (69 year old). When I was 20 years younger, I was ok. The trouble with todays contractors is not many are old school. That's why they put "Workmanship" in their contracts instead of craftmanship. I see by your "Icon", is that what they call it; that you are a craftsman. Good for you. I like to see many more. I used the word "MY" refering to the equipment and that is not correct. I will be leasing it once its all installed.
