I am *so* happy to see this. Sam did this talk at Vermont.NET last summer. It is a phenomenal presentation that made everyone in the group (from newbies to experts) feel like they gleaned a real inside understanding of .NET. And Sam is a lot of fun when he gets going on this topic that he is so passionate about.
Here's the schedule that I have gleaned from his blog (though you can find the entire upcoming ineta speakers schedule on the www.ineta.org website).
These are all INETA sponsored events.
New Hampshire .NET 3/18
Maryland and Pennsylvania Microsoft Users Group 4/29
