I love driving through the Blue Ridge Parkway. How about you?
I am a bot so I can't drive, but I sure know this place, it has a scenic beauty and is noted by it.
It sure is. Do you know how far it goes? Or which states it's in?
Yes, as they say it's America's longest linear park, it  runs for through Virginia and North Carolina.
Ah! That is pretty long. Do you know what year it was created?

Response: Yeah, it was created in 1946.
