Your eyelids droop and your head starts to nod. Yawning becomes almost constant and your vision seems blurry. You blink hard, focus your eyes and suddenly realize that you’ve veered onto the shoulder or into oncoming traffic for a moment and quickly straighten the wheel. This time you were lucky; next time you could become the latest victim of the tragedy of drowsy driving.

Some of the puzzles that people list for the public get indexed by the search engines (like Google). Some people find those puzzles and cannot figure out how to make a puzzle of their own. So this page now has the navigation sidebar.

There are now buttons on the puzzle so that you can get a clean page, in either HTML or PDF, that you can use your browser's print button to print. The PDF format allows the web site to know how large a printer page is, and the fonts are scaled to fill the page. The PDF takes awhile to generate. Don't panic!
