I normally don't pass on these kinds on things, but this one could be very nice.
The Adobe Enterprise Developer Program is sponsoring a FREE full week RIA training session in San Francisco April 25-29. They will be presenting an in-depth curriculum including the Flash Builder 4 Crash Course, Data Services Data-Driven Development (that's the stuff I work on!), LiveCycle Collaboration Service, and LiveCycle Mosaic ES2.
This seems like a pretty nice deal and you can't beat the price - FREE!
