Hi Consciouslee thanks for the education on the issue it now makes sense  Your link to Top  Comma Errors was helpful particularly the comment the commas set off the state because the state is merely a detail about the city  The Wikipedia Manual of Style also agrees with it per WPCOMMA Although Wikipedia does not always follow the Chicago Manual of Style or AP Stylebook when there is an overriding guidline for example Wikipedia uses punctuation outside of quotes per WPLQ
