years ago, I used to take my nannies to a very large B Sannan. Lady kept 4 nannies and him in her garden, which was large, but they had no grazing. She used to take two goats at a time down to the village park, on leads. They would graze, while she collected them branches!! She walked along a main road, quite a distance to get there.
The thing with walking goats is that you either don't get anywhere, as they stop to eat all the time, or they pull you along dead fast wanting to get to the next tree to eat it!!!
