What's a BarCampBank you ask? Here is a great post on Open Source CU by Brent Dixon that sums it up perfectly.
I attended BarCampBank Seattle in July of 2007 and it was a tranformational event for me. In 2008, there are a total of five happening throughout the US and the reports back from San Fransisco, New England and New York have been stellar.
I believe BarCampBankBC will be just as exceptional. And for $25, what have you got to lose?
