Selling the usual beach hammocks - anything with a bird on it - from postcards to T - shirts, place mats to books, and the shop is profitable to the owner and an antidote for most visitors' insatiable urge to consume. My inquiry to the shop attendant as to the availability of t - shirts with images of the plastic owls on them was not received with the same levity with which it was delivered. The formal wartime bunker or hunter's blind image of the centre is actually an all too accurate representation of not only Ducks Unlimited's philosophy but also the evolving relationship between humans and the natural environment or, for that matter, the urban environment.
