Walk into Irene's on the Atlantic City, N.J., boardwalk, and you'll find quite a product selection. You can buy a bottle of sunscreen, a bagful of plastic trinkets and, if you like, an iguana.

The 63-year-old gift shop has sold only two or three of the scaly pets this summer, but that's not the point. The iguanas, like so many features of this seaside gambling mecca, are there to bring in visitors, along with their wallets.
