What happened to the Milkman?

Got Milk?

Growing up I remember the milkman coming to my Nanny's house
delivering milk, orange juice, coffee creamer, eggs and butter. 

What happen?
This had to be in the 80's
and in the city of New Orleans.
 I must investigate further.

I am so excited about this capsule collection for Banana Republic
I am going down to the local event here in Atlanta
