Saturday: Clarendon Day

This weekend marks the 15th Annual Clarendon Day, which celebrates one of Arlington's hippest neighborhoods.

Clarendon sure has come a long way.

"It was nothing like it is now," said Matt Hussmann, executive director of the Clarendon Alliance.

Hussmann credits Metro's Orange Line as key to Clarendon's and adjoining neighborhood's growth. But he also credits local leadership for Clarendon's appeal.

"It's only genius if you can make it work," Hussmann said.

Clarendon Day was originally founded as, and still is, a way to support local businesses, bring people in to showcase the neighborhood and unite the community. This year features a number of bands on two stages, craft beer, food from local restaurants, more exhibitors than last year and plenty of activities for the kids.

"People appreciate the tradition of Clarendon Day," Hussmann said. "A lot of things we keep doing because people like it."
