I've got some riverside property in Brodgar. If you are not aware, Brodgar has no perimeter walls, so we often have the problem of people dragging animals through the streets to destroy property and kill people. There will be a wall around the main part of my plot, but I would like to have a 'patio' on the river-facing side that is enterable by strangers but not animals. I don't plan on putting valuable things on the patio - just basic tables chairs boats and cheap decorations. My idea is to surround the patio with some sort of barrier which strangers can get through/around but which is indestructible to bears. If players destroy the barrier themselves that's OK at least there will be scents from that.
The only things I can think of are... boulders? trees? Not sure... I need help brainstorming.
Fences definitely wont work - destructible by even just boars.
Palisade wont work because it keeps out players.
