13. Not really. It's a development and I've got .42 acres - third largest in the neighborhood.
I built a fire pit out of stacked bricks (no mortar). It's large enough. It's also an hour mowing job. We own the house outright (no mortgage) and probably will never leave it. But I like fire pits. I've always liked open fires. We've got a vent-less gas fire place in the house but we rarely use it. We go outside for that most of the time.
Ever had a fire in a ring of snow? There's nothing better.
