Why not? It depends on how far you are going though. If you are close to home, no biggie, of you want to call someone to get you if something happens, though rare, or walk home. For me, I carry a multi tool, and other tools, all the time. Of course I am sometimes touring so it makes more sense. Even so, I am often where there is no cell signal, and 30 or more miles from home or my car.
