More than 20 Washington Nationals players and team personnel will be at the Walter E. Washington Convention Center for NatsFest.



The team says the event scheduled for Dec. 13 will include question-and-answer sessions with players and Nationals staff. Members of the public will also be able to take pictures with players and the team's Racing Presidents mascots.



Advance tickets to NatsFest can be purchased online at the Nationals' website. They cost $20 for adults and $10 for children 12 and under. Prices increase by $5 on the day of the event.
