Good afternoon all, This is Leona Angotti I was retrieving our mail at the front entrance mailbox unit, about 4:30 this afternoon and noticed a set of keys left in one of the units. To avoid a chance of mischievousness, or a stranger picking them up, I brought them to our home. Please feel free to call me at (210) 854-2749 or come to our home at 9103 Limestone Pass to pick them up. Please provide a description of the keys or the #unit for your mailbox delivery.
