I’m not sure whether these DC areas rallies were all that well publicized. I actually looked for 2 weeks for news of local car rallies and never found anything on social media until yesterday.
Well in defense of the Baltimore, they did not do anything until last week or so. They scrambled to arrange something. So I did not find out about it until here on FR the Capital was mentioned in the MD page, then the issue of the Baltimore came up. THIS WEEK! So I was not aware until a few days back.
