If you have the time you can use GOOGLE MAPS street view and literally drive the route you want to see at the street level.
We do this sometimes to check out new roadways to us.
We also use GOOGLE MAPS to check out new to us RV PARKs... Gives us a great bird's eye view of the camp sites you may to make reservations for. Of course some places are totally covered by trees and you don't get to view much. ELKMONT in the SMOKY MTNs is such a place. I think you only get to see one short maybe 50-foot road area due to the almost 100% tree cover over the entire camp ground.
