Then fill the holes with snow, compact it firmly, and pour water on it. Shortly thereafter the snow will freeze to solid ice, and your tiedowns will be ready for use. This system has worked very well for me over the years, and several times has easily withstood extended winds gusting over 100 knots. Needless to say, every time this technique is used, your ropes will get a little shorter, for you have no choice but to cut them free just above the surface prior to leaving. In summer, when the winds are not so fierce, you do not have to take the extreme precautions that you would in winter, but then, putting in a good temporary tiedown is also more difficult.
Driftwood logs, if they are heavy enough, or partially buried in sand and gravel, also work well.
Otherwise, holes will have to be dug, and chunks of wood buried to serve as anchors. Whatever the situation, you are going to want to tie your airplane down if wind is on the agenda. Elaine said, gesturing out her side window as we taxied past a row of airplanes on the Tucson ramp. I was many years, another marriage, and 2,300 miles away from the incident reported earlier, and we were making like snowbirds and spending the winter in Arizona. Elaine sadly shook her head.
