When the trees go bare in winter, you may feel suddenly, uncomfortably exposed. Offset that effect with a privacy fence. Here, solid anchors are a must, so you'll need to set footings—and this must be done before the first freeze. Meeting that rapidly approaching deadline won't be a problem if you're properly equipped. Combine a posthole digger with high-strength Rapid Set Concrete Mix, and in just one weekend you'll probably be able to set all the posts you'll need to support your fence panels.
