Went to that first exhibition at RFK, then the first at Nats Park. Memorabilia from both, as well as a framed Wilk jersey, and a few auto'd MLB balls (from the likes of Brandon Watson, Daryle Ward, Marlon Anderson, etc...). Also have a Nats hardhat from during the build. Pretty neat piece.
Wish I could be there for the first playoff game! Texas transplant too
