Of course if I were making this trip on a weekly basis (or even monthly) I might be in full agreement with you. However, the objective is to limit crowd size, personal contact, and the spreading of Covid 19, so I hope I would still fall on the side of limiting entry. I would not like to think that my "selfishness or sense of entitlement" had led to the death of anyone, especially a family member or friend.
My issue with ticketed entry is NOT that this is being done to reduce transmission of Covid. It is that the pandemic is possibly being used as a reason to start a permanent reservation system that is NOT going to go away when the pandemic is no longer a threat. As I said, the idea of entry reservations has been tossed around for at least 30 years, but has always been canned because it is a fundamentally unpopular idea. However, I fear that the NPS is using Covid to get their ‘foot in the door’ (so to speak).
