What do you tie your awnings down with?

I use two of the corkscrew anchors mentioned above along with two rachet straps and two rubber type bungie cords looped over the awning roller at the top. The bungie cords allow you to put tension on the straps and keep them from coming loose. When camping on concrete, I replace the anchors with two 5 gallon buckets filled with water and covered with lids. I simply hook the rachet straps to the handles of the buckets.
