I live in rural Coweta, I wouldnt leave any mail out in my box to be picked up unless I sat and watched it til it got picked up, especially with a check in it. Alot of scoundrels around here. I would take the time to take it to the box personally and drop it in. Like DeerAssasin I hardly ever use personal checks except to give the ol lady one here and there for her church stuff, I pay all of my bills online on auto pay. Good luck with it.
