Hello all! For camping, we booked a spot at Lower Pines at Yosemite for one night. We want to stay two more nights but all the other nights have been booked. We will be traveling to the area for the first time. So, what would be your best suggestion for us to find a spot Thursday morning and Friday morning for the first-come-first-serve camping grounds? Which campground should we try first? I have heard information about the Ranger, but then I have seen some others where we should directly go to the camping ground so we are confused.
