Hey Mike thanks for dropping by. I know what you mean but one needs to fight that funk. My wife is right as she says I need to learn how to manage my time better. I retired 13 years ago and it feels like I'm busier now with the granddkids and other hobbies than when I was working. 
I'm about to get on the Nam GB with a very nice Trumpy Thud so I have been researching my subject first but can't wait to start it.
