Thx. I thought I'd have to leave it up all year -- not an option for me. I just have to hope for no rust issues. We are putting up the rectangle today, which is only year two on this particular pool. Still putting down the foam, so haven't seen how the poles and liners did over winter. Boy do I dislike the "put up" and "take down" weekends, but the kids' smiles make it worth it.
