House keys are a strange item for me to deal with when traveling. You need to take so you can lock up, and you need them when you return, but for the whole trip they are unneeded. So unlike credit cards or ID, there's no good reason to carry them on your person while away from your hotel.
So, what's the best thing to do with keys? I have no set place I store them. Sometimes it's in my suitcase mesh, sometimes in a backpack pocket. In both cases they are loose and tend to shift around a lot. What's a better way to store them to keep them safe and out of the way for the trip?
