Wayne's worm

Wayne Hill has upped the ante with his worm.

I began with a car and a tug-boat, Wayne countered with 'Sluggy'. Our intention is to attract the attention of Riverton's kids and provide them with something to look at as they scoot by. I've a bag of ready-mix concrete and am thinking about my next move...
