Aesop, two dozen centuries ago, allegedly wrote that you couldn’t make a silk purse out of a sow’s ear. (Or perhaps it was more recent and it was Bill Shakespeare and it was a velvet purse.) Modern science, either by evolution, revolution, or glorious accident, has proven that now it can be done. That transformation is exactly what our Island needs. Both Oak Bluffs and West Tisbury can be considered to be in the phase known as the sow’s ear.
