Hi all. Every year, I store our tiki torches away in our shed, but quite honestly, it's a pain to drain the fuel, pull the torches up (about a dozen), store them, then re-fill and re-install in the Spring (the posts go into a decorative rock border so difficult to drive into the ground). Does anyone know of weather proof covers that would go over the torches and perhaps have an elasticized or tie bottom (so they don't fly off) so that I can leave them out all winter? Thanks!
