I'm getting ready to close my AG 33' round pool for the 5th year. The most frustrating thing about it is effectively getting the winter cover pulled over the air pillow. I tie the air pillow off with 3 lines to the pool was supports. Inevitably, either myself or wife end up in the water to help the cover over, which sucks. If we don't, then pulling the cover puts too much stress on the lines and they break. Do you have any tips to make this year less frustrating?
