Shove a quick black banner at the top of your page when you're on a server other than production...
<% if Rails.env != "production" %>
<div id="staging-server" style="background: #000; text-align: center; color: #FFF; font-size: 16px; font-weight: bold; text-transform: none; padding: 10px 0;">You are currently using the <%= Rails.env.capitalize %> server</div>
<% end %>
