A long private road/driveway like some have just need a gate ... once entered .... no turn-arounds, etc. are typical.
There is no substitute!
"Private" - .... that can't mean me .... evidently
I went down one two weeks ago ... being nosey. Musta been a 3 mile round trip .... a dirt driveway in my youth.
"Toady" used to live down there .... next to our family farm. Now one of his relatives does....
I'd just tell them I was an "xxxxx" and we would have chatted .... didn't see a soul ....
Waved at relatives on the way out .... they don't know my white F150... but they wuz watching .... country neighbors

.
I waved bigly....
