Another good reason for taking down flags before hurricane force winds hit is that flag poles have a wind rating with flags flown and the flag pole alone.
I started shopping for a telescoping flag pole that could be carried in my RV. Telescoping flag poles have a much lower wind rating than one piece poles when used as a flag pole in the ground at home
I hope you don't drive the freeways with your flag raised...........most overpasses are only about 13' - 15' high.
