One problem is that you've just redefined the "city" key for this
hash.  So you'll end up with Savannah but no Atlanta.

When I cut-and-pasted your text and did a YAML.load on it, it worked
fine (other than the logic error with the "city" key).  Do you have a
tab character in the file somewhere, instead of leading spaces?

Try this and see if it prints 30328:

str = <<EOM
ga:
   name: Georgia
   capital: Savannah
   population: 1 mil
   cities:
     Atlanta:
       zip: 30328
     Savannah:
       zip: 30304
EOM
require 'yaml'
info = YAML.load(str)
p info["ga"]["cities"]["Atlanta"]["zip"]
