Thank you Perchiegirl and Primrosemom!! I have bungies on it now but was curious as how other ppl do secure them. I have a tarp covering about 1/4 of my run top and half way down the side now and it lifts now and then with the wind but it's as tight as I could get it. I plan to move it down on the west side of run to make a wind break before the snow flies.
Can you fit it flush to the run and zip tie it instead of flaps for the winter?
