Looks like the Antelope Valley Astronomy Club and the Ventura County Astronomical Society both have star parties in the area. But the ones currently listed on their websites direct people to the parking area on Frazier Mountain Road behind the Chuchupate Ranger Station.

That does not help with the tagging though. My guess would be one node per club/group with the following tags:

club=astronomy
name=Antelope Valley Astronomy Club
website=https://www.avastronomyclub.org/
description=Star party location
