Here is a list of things that I think you should have with you for a emergency.
-A pocket knife.
-A pair of gloves.
-At least three ways to start a fire (That will last)
-A rain coat or a parka. Too keep warm and dry.
-A phone to call nine one one. In a emergency.
-Lots of water. To last a week at least and to stay hydrated.
-Some long lasting food or dry food.
That is five things to have in a emergency.
