I did it when I was a teen and my sisters live in Rockville. I don’t think the train tracks have moved.
taken the subway you mean? no, it will be fine. probs LOTS more expensive than it was, but beats the headaches of parking and traffic. xsgirls took the subway to the Caps game last Thurs and xsteen and her bf took it on Saturday. Event parking is $25, so it’s def cheaper!
