Puppet users - Apr 2013 - what's the syntax for converting the yaml of facts into a hash table?

Hope I''m not being too thick about this but I''m having trouble
creating a
Hash from my server''s Facts.

I''ve tried the following: 
  facts = File.read( "#{puppetdir}/yaml/facts/#{certname}.yaml" )

  factH = YAML.load( facts )               # fails
  factH = YAML.load( facts ).to_hash   # fails

It looks like the facts file is a yaml of a Puppet::Node::Facts but I
can''t
figure out how to access it''s contents.

What''s the proper syntax for extracting the Facts into a hash?

Starting to get some clarity but still need help. Using YAML to load Facts 
produces the YAML object below. But I''m still not clear on how to
access
the contents.

myFacts = YAML.load( facts.yaml )
print myFacts.inspect

###  output:

#<YAML::Object:0x7f550d6c6858 @class="Puppet::Node::Facts", 
@ivars={"values"=>{"timezone"=>"UTC",
"puppet_vardir"=>"/var/lib/puppet",
"macaddress_eth0"=>"00:50:56:8D:4E:95",  ...

Spelunking through the code leads me to think that the following should 
work, but it doesn''t:
   print myFacts[''timezone'']

YAML.load_file("facts.yaml")

Oh yes, I forgot the first line of my snippet. But I still don''t have a
working syntax for reading the facts from that object.

  facts = File.read(filename)
  myFact = YAML.load( facts )
  print myFacts.inspect
