I cover a few as well. I have been doing it for years and years. Not enough that I think it's worth the investment in something more permanent though. I tried to get most covered yesterday evening. The stuff that was sheltered from the wind anyway. I'll have to go check and make sure they're still covered, and cover the more exposed stuff this evening. That's what sucks is doing it in the wind and cold. Oh well, it doesn't really become annoying until you get 7 freezing nights in three weeks, all seperated by 2 days where you have to go pull the cover only to put it right back on.
