A-Day is mostly for your support group and/or family. They get a chance to see you, hug you ask too many question. They will have gone through a lot of planning and expense to be there with you.
On the other hand,......you...... will know your limits to your right and to your left. You'll want to get away from WP and being under the ever present eye of upper classmen. You're going to want to sleep, get out of your uncomfortable uniform, decompress and eat. You don't want to think about what time you must be back.... but you'll constantly check your watch.
And you'll question yourself and doubt yourself. Then you put your game face back on and endure the next 4 years and understand everyone who has graduated from United States Military Academy went through beast.
In the past you couldn't travel more than 75 miles from USMA and you had to be back by 11:00 pm. You may have Saturday and Sunday to get away.
You'll do well! Don't dwell on the past..... look towards what is in front of you!
