Building fenceline so that rescue animals can have more enrichment

We will be building a wire fence to allow equines to have an extra field to roam. This will allow them the safety to roam unsupervised but also allow them to explore a new space for enrichment. We will have someone from our organization guiding the project. We will be clearing the area of limbs/brush, banging posts into the ground along with attaching wire to posts. No prior experience required.
