Here on the Space Coast I use flags to help me judge wind speed. Whether or not my kite will lift my camera or merely drag it along a grassy field, unable to lift it, can often be easily foretold by the flutter of a flag on a pole. Wind direction is easily observed by the waving of a flag. Flags are everywhere, from gas stations to schools, to the post office; they are easily spotted from almost anywhere. With a little bit of trial and error one can quickly learn to judge his or her kite's lifting ability in any given wind by the intensity of a flag's flutter.
