A lack of goats on the trip should significantly lower my stress and confusion levels, as well as increase my flexibility regarding departure time on Sunday. Consider: Prius rather than Dakota-plus-trailer means a much faster and easier drive, and no goats means no requirement to stay until 5 PM on Sunday before springing my babies. I will also be less worried about where I am and what I'm doing during the weekend.
My car won't be completely empty, though. I am planning (hoping) to take some of my fleeces up to the show, for competition and sale. This requires skirting those fleeces a little better than they already have been done. And with what free time? Argh.
