Video to see the drive to the top of Bell Mountain. Not only is it steep & winding, most of it is wide enough for one car only so when meeting someone coming up/down, one driver has to scoot as much to the side as possible & wait.
Gates seen at minute 6:27 (note this is one car width, there is a slight pull-off area to the left of this screen shot but only a couple of cars could park there to wait for the gate to open, imo) --

Road leading to the second parking area is at minute 9:35. It does look like there is a second set of gates there (between parking lot one & parking lot two).

You can see the observation area here. I believe that it was said someone who was hiking/from the observation area found Q & N.
