My guess is he was out helping the homeless and picking up trash . He found a Lotto ticket and cashed it in good for many hundreds , Said he was going to give back to the community ,, Went and got a new fridge , oven , a chest type and up right freezer , and a 6 burner gas cook top with bilt in Wok , Had them installed .
Now to kill two birds with 1 WGT rock .
My guess is that wanting to do better than just recycling the " Box,s " from that fancy kitchen he now has ,, He put the box,s on the tree lawn with a sign that said free home to the homeless ,
EDIT : Sorry my bad .
