API extract for state_place_name?

Observations don’t store the name of the country/province/state/etc. where they are located, they store the place_ids as a list of integers. You can either take the list of integers from an observation and ask the api for further information about those places, or what I would suggest is to download the full list of iNat places (http://www.inaturalist.org/places/inaturalist-places.csv.zip) and find the place_ids that you’re interested in and work with the ids. See https://forum.inaturalist.org/t/list-of-u-s-county-codes/50439 for a similar question and method.
