On one of our trips to Guemes Island last summer (a five minute ferry ride) we did find a few barns. The island is now mostly homes built for retirement or vacations, with farming giving way to newer houses.
A new roof on an old barn
Probably a chicken house rather than a cow barn
You can't tell the inside from the outside - the grass has overgrown everything
We did see a large field full of commercially grown blueberries - perfectly ripe - can't wait for this year's berry crops.
Poor old abandoned barn.
