We definitely encounter some wind here on the front range. I'll go ahead and put the cover on that one. The rest don't see to be an issue. Thanks for at least letting me know I'm not the only one. We had some good gusts yesterday and everything stayed where it should. One thing I didn't mention is I have in the past had both the upper front wall vent and the lower rear vent open and now I have them closed. I wonder if that had anything to do with it.
