Want to use a different layout for one page

I've installed Adventurous Pro on planobarber.com and have set the layout to a sidebar on the right, which is what I want on most pages. However, on the /location page, I want it to be full-width without the sidebar. I did this with my previous theme by changing the template for that page, but the only templates listed now are Default Template, Blog, Three Columns Sidebar Template, and Three Columns Template.
