You'd think it would be easy to start a tugboat museum. First, get an old tugboat. Clean-up some rust with a pad of coarse steel wool, slap-on a coat of paint, and presto, you're ready to sit in the booth and sell tickets. Everyone would applaud your efforts because, first, everyone loves tugboats and all they represent - solid construction and earnest purpose, hard work and benevolent contributions to civilization. And second, because old tugboats, all spiffied-up, are handsome sights, an alluring environmental decoration wherever they're found. And third, because the design of tugboats, like most of society's tools, has undergone great change, and the old ones are dying-off fast. You'd think everyone would support your labors at preserving a noble cultural heritage.
