"-For essential employees traveling to and from work during the curfew, police recommend having a valid picture ID and a note from the employer explaining why the employee needs to work during the curfew."
I fly in Tuesday 5 minutes before curfew. I haven't seen my family in a month and now I will end up spending the night at the airport. I moved to Baltimore a few months ago and I already can't wait to move out.
