The Pearl Art Gallery Map improved

The Portland Pearl District gallery map now uses the Layers feature of Acrobat 7 to allow you to control what classes of information are displayed. So for instance, if you don't drink coffee and only use mass transit, turn the coffeehouse and parking layers off and the map becomes more personalized and less busy with excess information.

ps--If you use some other PDF viewer like OS X's Preview.app or an earlier version of Acrobat, then you won't be able to take advantage of this capability.
