Just got an email from Trader Joe's that the Silver Spring store will have a grand opening celebration June 3rd, though I've read both May 20th and May 27th here.
It might already be open and this is just the party for it. The email said "opening very, very soon". The email also said a store would be "opening soon" in Pikesville, Md., but didn't have a location. Maybe that former Sutton Place mentioned here before.
