Are you nervous when you see NCWEE? concerned when you see CIRC? perturbed when you see PBC? Visit Mr. Hansen’s fabled abbreviations page to make sense of those cryptic markings you see on your papers.

Field trip to the National Cryptologic Museum, Fort Meade, MD. Bus will depart at 8:00 a.m. Bus will probably be loading in the area near Satterlee-Henderson Field, but stay alert and try not to miss the bus! Attendance will be taken. If you attend the field trip, you are excused from A through E periods and the first half of F period. If you do not attend the field trip, you must attend all your classes except for STAtistics.

Note for seniors: We will be back in time for you to attend the Mother-Son Luncheon. Mr. Barrett is aware and has approved of our schedule. The luncheon begins at 12:30, and we should be back within a few minutes of that time.
