Hope the Weatherman is WRONG!

My Going to Houston yard sale is this coming Saturday - and they're predicting "scattered thunder storms" from Wednesday to Saturday. I'm praying the storms will have played themselves out by Saturday. Groan!! I have a one car garage which is myshop/studio and no porch. AND - I just received another mega-donation from a neighbor. I'm living in a warehouse. I have enough clothing to outfit an army. I can see me having enough left-overs to do this again next month. But right now, I have to devise a Plan B.
