All you have to do is buy a pair of binoculars. No financial interest in this. I just think it's a fine idea. I wish more vendors working in the birding field would do the same. Duck-stamp money buys bird habitat.
From a message I received earlier today: If you buy a particular brand of Steiner Binoculars, you will be given a duck stamp and a membership in the National Wildlife Refuge Association.
