I was contemplating going in and doing any training because of my elbow anyway but then I discovered that my hot water tank decided it had made enough hot water and quit. SO I took a very quick and very cold shower and went to work. I called a friend who does HVAC and plumbing things for a living and he and I are going to replace it tomorrow. I could probably figure it out on my own but it would involve 100 trips to the Home Depot and while I'm sure it would work it probably would be right. It's good to have good friends.
