I have a backpack that I EDC. I voted for the "carry with you at all times" although I don't really carry it all the time. Actually, I don't carry it even nearly all the time... I don't carry it at home and neither do I carry it at work, I leave it in my locker. But when I walk out the door, I usually have it with me, except when I'm just taking out the trash or going for a walk with the dog or some such. So "all the time", yeah right... If it amounts to an hour or so each day, perhaps a bit less, let's call it 3-4% of the time. So the literal-minded among us might say that I hardly carry it at all. But it's still my EDC pack, I do carry it every day, just not all day.
