What would you do with the alpacas? Weave their fiber into clothes? Be sure to have some usefulness for them besides just a tax break.
In PA, you are required to have 10 acres as well as the livestock to qualify for tax abatement. GA may be different.
But remember, they'll need to eat more than just the grass you have growing...
It seemed to me that the earth may he borrowed but not bought. It may be used but not owned. It gives itself in response to love and tending.... But we are tenants and not possessors, lovers and not masters.
