Often Gates will seat in Mammoth Caves - in worlds approximating Earth as we know it.
This is a thumbnail of the area as it appears in the real world, for reference
Mammoth Caves is a National Park in Kentucky and has a Ranger station attached to it. In healthy economic times the Caves are a tourist attraction, with Guided tours. The ring station is in a hidden cave nearby that's cleverly concealed by trees and brush and covered by a hologram which steals ambient energy.
The path out is roomy and flat, you could drive a car out of it. But then you're in a forest, with trees and underbrush that would make travelling difficult. There are deer trails and hiking trails.
The gate is about half a mile east north east of the main camp ground and about 300 yards away from a hiking trail, 100 years of that is through dense trees.
Locals are used to seeing tourists and RVers from all over, so accents and odd clothing will not phase them. Visible arms may disconcert them. Hunting is forbidden in the national park
