There are some roads above that can get you a view but you will be a ways away. I don't recall the road number, ask Luke or Chuck.
Another option is biking in on the Santa Fe Trail and find a spot with a view. Could be the next best thing to a stadium seat. I have never seen any security at the trail gates but I don't know if that would change during heightened security.
I had the privilege of attending graduation last year. That was the first time I had been to a military academy commencement, I found it more moving than a typical commencement. If you ever get a chance to go to one jump on it. By the way the Thunderbirds put on an awesome show and hearing the announcer's descriptions of demonstrations adds a lot. Stadium fly over at the hat toss is way cool.
I am way too busy tomorrow or I would be tempted to join you.
