We have had some instances when the box has disappeared for a while, and luckily it has always popped back up. One situation that frightens me is where a member passes away while the box is in his possession. A spouse or other family member will most likely have no idea what the box is for, where it should go, or anything. Thus, we need to have a valid email address and phone number. In a worst case scenario, a phone call could be answered by a family member so that we can at least communicate and figure out what step to take next.
