I had remembered seeing Oprah have an island somewhere, so I found this:

Orcas Island

…We were surprised but it was believable given that every time we visit the island there’s news of another big celebrity sighting and/or real estate deal. US Secretary of Defense Robert Gates, Condoleeza Rice, Josh Groban, Kat Dennings, the list goes on.

Orcas Island is the largest of the San Juan Islands

The San Juan Islands are surrounded by major shipping channels.

Haro Strait, along with Boundary Pass, is the westernmost and most heavily used channel connecting the Strait of Juan de Fuca and the Strait of Georgia.

It is the main route connecting the Port of Vancouver and other ports around the Strait of Georgia with the Pacific Ocean.
