text: Tracking and Countertracking
  Travel in Streams
  I-66. While traveling in streams, avoid contact with anything that could catch and reinforce your scent
  such as a branch or rock.
  METHODS OF AVOIDING DETECTION
  I-67. To avoid detection--
  Wear Common Footwear
  I-68. Some types of soles, such as the ripple type, are uncommon, which allows for easier tracking. Flat
  soles leave less sign than treaded soles, but are impractical for traveling over rough terrain. Wearing
  sandbags over boots reduces sign. However, burlap rips off and leaves telltale sign, so watch out for this
  should you choose this method.
  Leave No Scent
  I-69. Avoid leaving scent. While in a position or on the move, leave as little scent picture as possible.
  Food, blood, urine, and feces all leave strong, reinforcing scents for a search dog. Be especially careful in
  areas where you must remain for some time and in areas that you know are patrolled by dog teams.
  Behave Unpredictably
  I-70. Go against everything that human nature tells you to do. Go into difficult terrain and behave as
  most people moving through such an area would not do.
  Practice Tracking
  I-71. Know your enemy. Practice tracking and you will notice things that you should avoid doing when
  you are the one being tracked. For the team to successfully countertrack as a unit, each team member must
  have a basic working knowledge of tracking.
