I sure can waste time.
Maybe it's because I work long hard hours to bring home the bacon, but I can really chill and do a lot of nothing at all when I know there's work to be done on the weekends. Yesterday I wanted to get outside and start getting stuff covered up before the frost hits, Friday being the average first frost date for my area. We are having a mild autumn so far, but I don't want to push my luck.
I never did get to the hardware store, though; I'll have to do that on the way home from work tomorrow.
As a note, the latest issue (December 2013/January2014) of The Mother Earth News has an article by Barbara Damrosch and Eliot Coleman on building a movable hoop house that looks the biz; check it out (instructions here).
