title: Nav collapse not working with twitter bootstrap - icon not appearing
body: <p>Im having the exact same problem as stated on this answered post - <a href="https://stackoverflow.com/questions/9624918/nav-collapse-not-working-twitter-bootstrap?answertab=active#tab-top">nav-collapse not working [Twitter Bootstrap]</a></p>
  
  <p>I apologize for being a newbie but I assume the answer here means that I should place:</p>
  
  <pre><code>&lt;link href="assets/css/bootstrap.css" rel="stylesheet"&gt;
  &lt;link href="assets/css/bootstrap-responsive.css" rel="stylesheet"&gt;
  </code></pre>
  
  <p>in the HEAD section of my application.html.erb file.  </p>
  
  <p>Well, I've done this and the icon is still not appearing.  Is there anything else I need to do?  </p>
  
  <p>Here's my GEMFILE source:</p>
  
  <pre><code>source 'https://rubygems.org'
