`  : Hi Consciouslee, thanks for the education on the issue, it now makes sense.  Your link to Top 5 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 WP:COMMA. 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 WP:LQ.  `
