You can't drive to see the first one, above. This is an old genuine snake cedar rail fence, probably one of the originals, built without fence posts, by criss-crossing the rails in a zig-zag pattern. As you can see, it's probably pretty old, because it implies the land on both sides was a field - today it's fairly mature sugar maple forest. Although there are thousands and thousands of old cedar rails lying on the ground out there where fences used to be, it's actually quite hard to find a fence like this still in place - though now serving no purpose other than being a bit of history.
Much more common are old cedar rail fences that have been rebuilt, often with pairs of vertical rails used as fence posts, and the rails wired in place in between them. And often starting to fall down where they're not maintained, like this, but still an attractive part of the rural landscape.
Next come the nicely rebuilt and maintained cedar rail fences, usually used for landscaping around rural homes. We have a short stretch of fence ourselves, just because it looks nice. Rails themselves are getting valuable; gathered up from old field edges where they're lying on the ground, they'll bring $3.00 each now. I even saw one fence recently that was made of NEW cedar rails - that means they cut the trees and split the rails, a skill almost universally long lost.
Most more recent fences are the standard fencepost and page wire or barbed wire. This one is a combination, and seems to be kept up by just adding fenceposts every 2-3 feet. I expect some of the posts aren't even sunk in the ground, but just replace the verticals of normal page wire fencing.
Next time perhaps I'll dig out some of the old stone fence pictures.
