Somewhat related for parents of fall sports athletes (especially football), your A Day weekend experience will be different than what is commonly communicated here.
Most fall sports will be in the thick of preseason camp that weekend, so your cadet may have commitments that prevent them from visiting with you and/or leaving post due to team commitments. Our DS was able to have a late breakfast with us Sunday, but otherwise not able to unplug and spend time with us. (For logistical reasons some new cadets were actually not able to attend the A Day march.)
If you cadet is a fall athlete, make an effort to connect with upper class parents for the particulars of your sport. Likely a Facebook group for most of them. For football parents, your cadet will basically leave camp for the march, then head back to Michie to suit up for the rookie scrimmage. After that they will have a full afternoon and evening of meetings, films, training, etc.
