 - Location (`--loc`): The general location of the repeater (for example, `Seattle` or `Buck Mtn.`)
+- RepeaterBook State ID (`--state_id`): The State ID of the repeater on RepeaterBook (an integer you can find after `state_id=` in the URL).  Defaults to Washington (53) if not specified.
 - RepeaterBook ID (`--id`): The ID of the repeater on RepeaterBook (an integer you can find at the very end of the URL)
 - Callsign (`--call`): The repeater's callsign (for example, `WW7PSR`)
 - Frequency (`--freq`): The repeater's frequency (for example, `146.960`)
