I believe 04-023 was originally allocated for police intersystem use out of Orange County. The usage migrated to an area wide special events channel. For example I have heard PD coordination of traffic control and such on 04-023 when a movie is being filmed in Kingston. Activity on 04-023 is sparse these days and mostly it is dead. It's not unusual to see affiliations to 04-023 but voice traffic is far less common.
