Registration for the US Dev Days 2004 is now open, and if you register before February 10, it's only $75.  Coming to 32 different US cities, it's sure to be interesting and rewarding for professional developers across the country.  From the site:

With a focus on building secure smart client and Web applications using Microsoft® Visual Studio® .NET, this event will help you add power and security to your applications the moment you walk out the door.

No matter which track you attend, you'll be able to see a local expert build a real-world application, see the application in action, and leave with the code at the end of the day.
