Rails 3 telling me route doesn't exist

-- category.rb

class Category < ActiveRecord::Base
  has_many :subcategories

  validates_presence_of :name
  validates_uniqueness_of :name
end

-- subcategory.rb

class Subcategory < ActiveRecord::Base
  belongs_to :category
end

-- categories_controller.rb

def show
@category = Category.find_by_id(params[:id])
respond_with @category
end

-- routes.rb

resources :categories do
  resources :subcategories
end

-- categories/show.html.erb

<div style="padding: 15px; background-color: #D8AEB5; width: 100%;">
  <%= link_to "See all Categories", categories_path %>
  <span style="float: right;">
    <%= button_to "delete this Category", category_path(@category),
        :confirm => "Are you sure?", :method => :delete %>
  </span>
</div>

<h1>Category: <%= @category.name %></h1>
<div class="card">
  <table id="sub_categories">
    <tr>
      <th>Sub Category Name</th>
      <th>&nbsp;</th>
    </tr>
  <% @category.subcategories.each do |category| %>
    <tr>
      <td><%= category.name %></td>
      <td>&nbsp;</td>
    </tr>
  <% end %>
  </table>
</div>
<div id="default" style="background: none repeat scroll 0 0 #F9EDD8;
padding: 5px; width: 98%">
  <%= link_to "Create a new Sub Category",
new_category_subcategory(@category) %>
</div>

Here is the error I am getting. I've tried recreating this resource,
re-doing the routes. Restarting mongrel.
undefined method `new_category_subcategory' for
#<#<Class:0x4a5ec34>:0x4a5d600>

Does "rake routes" show anything helpful?
