The garage has an attic also. I don't even want to think about what we put up there when we moved in (and haven't visited since). I do remember that the movers, upon noting the cross-country skis and snowshoes, asked, "You planning to get a lot of use out of these?" This is what happens when a couple of Minnesotans move to east Texas.
Feeling resolute and virtuous, I will begin the cleanup tomorrow morning. I think.
