Tell me about it. I don't even care if he doesn't switch varieties on the fields that I didn't plant (no Variety Locator file) but I've showed him and walked him through how to change fields and select the guidance lines at least 25 times and every time he looks at me like the kid with ADD who sat in the back of the class. He's starting to understand it a little bit finally though, so maybe there's hope....until next year when he get's in the 70 series and has to learn the new command center like you say.

I need to get him through some training this winter. ugghh.
