I don't mean to be demeaning, but where are the illustrations. I have been preparing my CEU 2011 Change course for approvals for the last two months. The state of Washington requires 200 questions and I have been building 200 illustrations, one for each question. It takes me up to 3 hours to build an illustration and many times I have to go looking for something to take a picture of. I just wished they had those digital cameras around when I did 4,000 inspections for the State of Alaska from 1988 to 1996. I have put 140 of my illustrations online in slide jpg format at http://www.electrician2.com/2011nec1/2011_nec_ifchanges/2011_nec_changes.html
I still have 60 to go.
