I walked when I graduated four years ago, though it wasn't really a big deal. I also happened to be getting married later that day, so it was kind of overshadowed. I did have lots of family there, however, so that made it kind of nice. Also my groomsmen all showed up wearing tacky Hawaiian shirts (which to be fair I had given them the night before as a gag gift). It was a small school so it took under an hour. The graduation was at 10 am and the marriage at 2 PM; my wife was worried I wouldn't be done in time. In ended up going to IHOP in between and having a huge breakfast!
