I thought this was novel - using a very short (2"-3") section of paracord and a smallish hook (#8), you can fashion a lure to catch fish. Obviously you are going to have some paracord with you and if you use the hooks from your Doug Ritter survival kit you can make these out in the field. Note: This site has some other very interesting homemade tricks.
