File Description: AI Washington State Ferries on Puget Sound - UPDATE. This update adds two AI Washington State Ferry runs to the Puget Sound (Seattle) area. Added are the Edmonds-Kingston route and the Mukilteo-Clinton route. A previous installation of my Washington State AI Ferry package (ai_ferry.zip) is required. These have been created in response to a request from a fellow simmer who lives in the area. Please unzip to a temporary folder and follow the very simple installation instructions. Compiled for your flying enjoyment by David "Opa" Marshall.
