Hundreds of tribal dancers thundered into Centennial Hall on Saturday evening during the Celebration 2010 closing ceremony and grand exit. The packed event capped Southeast Alaska's biennial Native dance and cultural festival. Celebration was developed by Sealaska, the region's Native corporation, in 1982. It will return to Juneau in 2012. This year's event featured about 2,000 Native dancers and events held June 2-5 were expected to draw in about 5,000 viewers, according to event organizers.
