Go fishing if you can....I know I just came back from a 3 day fishing weekend and the first thing my wife said to me is don't expect to go fishing this coming weekend or you'll come home to the locks changed. It sounded like a Brad Paisley song, my response was well I'll take the van, at least I can fit everything I need in it
The point of this rambling is unless your wife is going to lock you out of the house if you go fishing, its best to get out and get the last weekend of the season in since the deck does not care if it is done this week or next!
I should add this of course is all in jest. I am not actually going fishing next weekend, and if that deck needs to be finished sooner than later, you probably should get it done.
