Box #3

I'm on my way to shipping giant box #3 in order to have a car ready to make the Madison trip. Is it worth it to install cross bars for my Jeep roof rack, to fit a cargo carrier? I still haven't gotten my last set of revisions back yet, so I'm nervous about getting those done. I'd like to get them done by Friday evening(?) so I'll be totally ready to leave on Saturday. Let the insanity commence.
