Single Page with No Sidebar

Hi folks,

I searched and read numerous topics but have not solved this one yet.

Using a child of Twenty Eleven and default set for page with right sidebar. There does not seem to be a one column choice. Just sidebar, default and showcase.

I want all pages BUT one to have this sidebar. Whenever I edit the page, no choice of template makes any difference. It always has the sidebar.

I created a new page template based on siderbar-page.php and now called Fullwidth. It appears in my choices, but the result still has the sidebar.

<?php
/**
 * Template Name: Fullwidth
 * Description: A Page Template that is a fullwidth page
 *
 * @package WordPress
 * @subpackage Twenty_Eleven
 * @since Twenty Eleven 1.0
 */

get_header(); ?>

		<div id="primary">
			<div id="content" role="main">

				<?php while ( have_posts() ) : the_post(); ?>

					<?php get_template_part( 'content', 'page' ); ?>

					<?php comments_template( '', true ); ?>

				<?php endwhile; // end of the loop. ?>

			</div><!-- #content -->
		</div><!-- #primary -->

<?php get_footer(); ?>

The site is

but no pages there have anything but sidebars. I leave that for a hidden test page.

Have a solution for why I cannot get this to work?

Thanks.
