MS is coming to Grand Rapids for a TechNet event - specifically - Matt Hester

If my schedule allows, which I hope it does, I'll be down there to see the demonstrations on May 16th. It looks like they will be talking about wireless security, network intrusions, and Vista. Since I plan on putting out 802.11x authentication when we move into the new building, this seminar might help out with that process.
