Notes
We drove the new US 301 toll road in Delaware. Even though it is a little longer, it saves on tolls and stress level from any route through Baltimore. There are times to avoid the Bay Bridge, like on Labor Day, where the backup was 14 miles long, but otherwise it should be better that going through Baltimore.
