Forgot to mention that in order for parents to put $$ on the Yard Card, you will need your Mid's alpha number, a 6-digit number that is unique to them during their time at USNA. First two digits are the class year, e.g., 16xxxx. Your Plebe will have this number committed to memory by the end of I-Day, since they will have to write it on every article of clothing they are issued throughout the day.
In the midst of all the emotions after the Oath of Office, I just made a mental note to ask my plebe what his alpha code was and jotted it down for future reference.
