HOW TO USE THIS MAP 
From it determine what zone you are in. Every item carrying your zone 
number or a smaller number should be hardy with you. If you want to 
gamble on those rated one zone greater, there is at least a chance for 
SUCCESS, but two zones greater will probably be hopeless. 
For full explanation of the entire system see inside of the front cover.
