I went to the SQL PASS 2007 Summit this past week, and I have to say that this was one of the best ones I have been to. I went to a pre-conference session with Kalen Delaney on Managing and the Reuse of Query Plans. Everything that I learned, I could use in my current work. That was very important for me as a new DBA in a project that needed this information.
Thanks to all speakers who took the time to put together presentations for us to learn from.
