What is Nick Doing?

Well I figured that it was about time that all of you got a glimpse of what Nick is doing while we are out here. For the past 2 months he has been memorizing maps that make up the airspace that he will be controlling. It is four maps, that are...well confusing. He could explain it so much better so if any of you are interested in learning call us and he can explain it to you better. But make time because it will take about three hours to cover even part of it. Anyway, I can explain part of it. The four maps are different altitudes and he has to know them like the back of his hand. To pass the tests he has to draw these maps from a blank page, so it's pretty difficult. They got about two-three weeks to study each map. Lets just say he is tired of drawing lines, triangles, and circles. I hope you enjoy looking at these and good luck making any of it out because I live with the man and I don't understand anything. Love you all have a good week.
