Late last fall, I lined my run with heavyweight shower curtain to "winterize" it. And what a winter it has been - colder, snowier, icier, windier.... Today I took the shower curtains down and am storing them for next year. They survived in perfect shape! I will definitely be doing the same thing with them next winter. Some pics of when I installed them back on OCTOBER 23rd! They were up for 4 1/2 months!
