So a certain unnamed goat, whose name rhymes with “Florio”, is the Harry Houdini of goats, and despite massive efforts keeps escaping. At first we thought there was a hole in the fence we were missing (there actually was), but then my daughter witnessed her just do a standing jump over the stone wall. So we had to put a fence on top of the stone wall, of course now she goes over that too… 
. She doesn’t actually want to escape, but she also absolutely refuses to stay in the pen, so after putting in the metal fencing we realized we needed to electrify it since she was becoming braver (she’s walking down the aisle in the barn where we were tacking up the horses); some of our horses freak out, my horse likes the goats (well in reality she mostly likes saying hello to her little friends because they have a full bale of hay sitting in the feeder on their fence).
So off I went to the local Tractor Supply and bought steel fence posts and welded wire fencing. I bought all the supplies to electrify the fence, with the guy helping me find the right insulators to got onto the posts. Of course tractor supply doesn’t sell (or at least stock) the correct insulator for those posts… .
So at first it seemed like a simple profile for the stamped steel posts. It apparently the designer was a horrible person and made the sections at arbitrary lengths and angles. So my first 3D printed prototype failed miserably. Given how long that poll laser cutting the profile in draft board was the way to go, so after 5 or so cutouts I found one that gripped the post well. Now I did actually have an entirely laser-cut design that used acrylic only rather than 3D printed, but partly the yellow plastic insulators serve to warn people the fence is electrified. I didn’t have enough yellow acrylic on hand to make them, so 3D printed it is, but the Glowforge let me get the profile in minutes instead of hours:
(How rude that she walked right past me as I was building the fence - no guilt there!)
I have seen photos of them in trees like a flock of birds. It is too bad you are too far north to grow bougainvillea though they might eat their way through even that.
