damn! 3 redundant same purpose action methods!

class BrowseController < ApplicationController
  before_filter :load_package, :only => [ :package_summary, :itinerary, :groups]

  def category
    @category = Category.find(params[:id])
  end

  def package_summary
  end

  def itinerary
  end

  def groups
  end

  def tour
    @tour = Tour.find(params[:id])
  end

  protected

    def load_package
      @package = Package.find(params[:id])
    rescue ActiveRecord::RecordNotFound
      flash[:error] = 'Package not found!'
      redirect_to root_url
    end
end
