Left rear pants pocket if I'm expecting work calls, inside left chest pocket otherwise. With the rest of the crap I carry, a pistol on the hip and spare mag in a pocket, not really worried about getting a phone shaped imprint on my ass cheek.
Hello, Stranger, can you tell us where you've been?
More importantly, how ever did you come to be here?
Though a stranger, you can rest here for a while
But save your energy, your journey here is far from over.
