We did Senior Send-On, and I still remember mine.

There were only three of us because it was right before the December graduation date (I graduated early). The thing that made it especially meaningful was the little bag of Wishes that our chapter advisor gave each of us. It was just a little purple chiffon bag filled with tiny notecards with a different wish for the future on each one. I scrapbooked mine and read them every now and again.
