Change cars? Fly instead?? Ha!
Seriously, the fine details of logistics for this kind of thing are far too complex and personal to go into on a forum like this. I intentionally limited the details to keep the conversation on topic. Driving long distances is something most of us do and the suggestions can also help others later.
Timing and such are still very much up in the air. We are trying to figure out how much time and pain we are willing to take and what bits of fun we can squeeze in to compensate. That's why I'm asking for input! Right now things are flexible so I can take advantage of new ideas.
I've started route planning on www.furkot.com (heard about it here,) because it lets you set drive time and/or mileage limits. Lots of 'what if' opportunities! Shortest route looks best unless storms brew up. Weather can foul any plans!
