If I use validate_presence_of then it the field is only considered valid 
if 'Yes' (true) is selected. Selecting 'No' (false) results in 
validation error.


After some reading this is what I found which is why I chose to use 
validate_presence_of:

"If you want to validate the presence of a boolean field (where the real 
values are true and false), you will want to use validates_inclusion_of 
:field_name, :in => [true, false] This is due to the way Object#blank? 
handles boolean values. false.blank? # => true"
