No tickets are required. The Parade is open to the public. Come early to get a good seat.
In previous years parents were given a card with their cadet candidate's CBT company on it. Last year the company was also sent with the parking pass.
keep that with you or memorize it. When you arrive early for the parade, there will be cards at the edge of the parade ground showing where the beast companies will line up. You can then get in the stands in front of there. If you can't find it, ask one of the cadets lined up to keep people off the plain. Be nice to those cadets, they are often cadets "voluntold" to help, and are often stuck on post due to remedial work or other reasons not in good standing (sometimes the stories are funny).
Then learn about Guideons, the yellow (and black?) flags carried by each company near the front in many parades. That's how you know when to madly shoot photo's as they pass!
It may still be hard to find waldo, but we were able to see ours march in, as well as found them in the photo's we took of the company.
Bring binocs if you have them, they help as well. If you find your kid, and the people next to you did not, loan them so they can get a chance as well.
Hold your breath when a new cadet stumbles, or passes out. And get a tear in your eye when their squaddies help them get back in line. (It seems to happen at least once each year). Smile when cadre knocks their hat off with a sabre, they are learning as well.
Then when it's done, don't rush out. Trophy point is a great place to look out, take in the scenery and let the crowd disperse.
By the way, you should also hit the cadet store and Thayer bookstore (if open) after seeing your cadet candidate off. If not on R-day, they will be during reorgy and A-day.
Learn where Washington road is, as that's where you'll want to be for Marchback in a few weeks! If you can, you should attend. I did not "get it" until they came into sight. What a smelly, tired, but proud cadets! And then the old grads marching behind. There was one I figured had to be over 80. I did not complain about my bad knee after seeing that!
