You have so many things to remember. One way to cope is to have things done automatically, and have things tied together; pretty much forcing you to have it.
Night falls fast to the unprepared.
While there is no darkness, just the absence of light, one does need a light source to make a go of this. But, you might forget to bring such a source.
To remedy this, have at least a pen flashlight in the glove compartment. Plus, get a key-chain flashlight. A flashlight will be with you at all times.
Say adios to darkness, until you want it. Light up the night. May the light be at your back.
