We will depart Seattle Wed. 8/14 to arrive in PA for the evening. We are flexible about departure time, but had planned to spend the day in Seattle. I see on the WSDOT that traffic is heavy from Seattle to Bainbridge until 8 or 9. Which route is better? Take ferry to Bainbridge or drive north and take the Edmonds ferry. Which is easier? Quicker? Very good chance we will be traveling by night, so a beautiful drive won't matter.
