The whole way up is a series of highways.
The only really bad city traffic we'll face is the home traffic around Washington, DC. Then it's pretty much countryside until the hotel. Maryland is the longest stretch of the journey. We go through Baltimore, but the highways are bypasses, so we skirt around heavy traffic. We get off on backroads to get to the hotel. Altogether it should take plus or minus three hours.
I really miss Shoes, too.
