Down here in Australia, Single Wire Earth Return (SWER) is common for long rural lines. They run at 12.7 kv (one phase of a 22 kv 3 phase line). At the consumer end there is a pole mounted transformer and a fenced off earth stake. It seems to work reasonably well even in dry conditions but you occasionally hear stories of a large quadruped coming to nasty end if they get inside the enclosure. Obviously there would be a radial potential field in the ground and on the surface and quite a voltage can develop across their legs.
