Adjacent to the Walgreens Grill Room is the photo & camera department. The latest and greatest thing on sale there is the Polaroid Colorpack II instant camera. They've got the price of a color Polaroid below $30 now (they used to be $100!).

The Colorpack II uses so-called "pack" film, which has eight exposures. You snap the photo, pull out a section of film, wait 60 seconds and peel apart the negative and print (disposing of the former). The camera can also take black & white shots (using black & white film pack).

If you're planning on taking any nighttime or inside shots, you'll need some of these Sylvania Flashcubes. Each cube is good for four flash pictures. You then throw it out.
