  <a href="http://deaconsofdeadwood.com/photos/" rel="nofollow noreferrer">http://deaconsofdeadwood.com/photos/</a></p>
  
  <p>On screens wider than 768px, the page is stuck in this position:

  <p>I have been picking at it awhile, using firebug and experimenting.  Not even going to tell you the weirdest part. </p>
  
  <p>Two goals here:</p>
  
  <ol>
  <li>Find what is wrong and a fix for the scrolling not working on screens wider than 768px.</li>
  <li>Learn something, so I can find this kind of fix on my own.</li>
  </ol>
