Re the guard on White Sands Road, we were there in November '21 when I believe the guard house was first put in use and the guards would be there from about 6pm to whenever. When we were there in April we didn't see anyone there until almost the end of our trip and when I asked about it, someone suggested that simple economics had forced them to change the service to later in the evening and again, until 'whenever'........ Truthfully this made more sense to us than having them there so early. We were usually in most evenings by ninish but the few late nights we experienced, they were there doing their checks.
