In the nearly 10 years that one Island war memorial has been mothballed in the artist’s backyard, tens of thousands of American soldiers have been killed or wounded in controversial wars being fought far away. Veterans hospitals have been overrun, new names have been given to the traumas of those returning from foreign fronts, protest groups have formed, a President was elected promising to bring troops home, promising hope and healing. And still the memorial has stayed away from the Vineyard public.
