commenting out the relevant lines in people.js.coffee and then opening up the
console in FF and executing returns...
Error: $ is not defined
Source File: javascript:%20$('tr:nth-child(odd)').addClass('odd');

No - I wasn't saying that.
This was my view code (which works) prior to my attempts to use jquery's
alternating table row scheme...
<%
odd_or_even = 0
for person in @people
odd_or_even = 1 - odd_or_even
%>
<tr valign="top" class="<%= 'odd' if odd_or_even == 1 %>">
<tr>
<td><%= link_to person.uid, :action => 'show', :id => person.id %></td>
... <% end %>
and this is what it looks like when trying to use jquery's alternating table
scheme...
<% for person in @people %>
<tr>
<tr>
<td><%= link_to person.uid, :action => 'show', :id => person.id %></td>
... <% end %>
