Replying to Missing out on College Graduation

So, I just learned that the second round of the national tour of jet ski races in Panama City, FL that I plan on racing this upcoming season is the same weekend of my spring college graduation ceremony. I am torn on which event to attend.

How big of a deal is college graduation? Would I be an idiot for not attending and not making a milestone in my life, or is this something that you'd be willing to brush off given my circumstances?

Just looking for some of your thoughts.
