The first U.S. flag was unfurled in 1777, and 100 years later Flag Day was created. Ever since on this day, many people fly Old Glory from rooftops and flagpoles, border to border and coast to coast. Want to put up a flagpole of your own? First, check local restrictions on placement and height. Next, shop for a pre-fab flagpole kit. Its sleeve base goes in first. The pole is added later, making it easier to install. First, dig a hole for the flagpole. Most kits give suggested measurements. Then add bottom gravel for drainage, and angle the bottom of the hole walls out to create a bell effect for better holding power. Use concrete mix; add only a few inches at first. Put the sleeve base in position and add more concrete. Use a level on the base, and mound the top a bit for water drainage. Let it cure overnight. The next day, bolt in the flagpole and muster up a proud salute. And that's the On The House tip for today.
