Yep. Guess you have heard that there is such a thing called "MySQL Conference 2008". In fact, this has been a yearly event. This year it would be held in Santa Clara, California on April 14-17, 2008.
But the question is should you attend at all? Well, if your company is going to pay for it, why not?! But if you are going to pay for it, think twice. Sure, you will learn a lot, but do you really need them especially since you are just starting as a MySQL DBA? Even if you are an intermediate DBA, it would just be for fun if you are going there... I'm not sure if the learning value outweighs the cost.
Anyway, check this out for details... http://en.oreilly.com/mysql2008/public/content/home
