Seems to me that the bottom line is you can't plan where you're going until the afternoon before. This isn't tracking a storm, it's looking for a clear(ish) sky and you can't predict that more than 12-24 hours out. I've been looking forward to this for 30 years and have run through a million scenarios and it keeps coming down to leaving home by midnight and heading for the choice spot to be there before most people and before local LEOs have closed stuff off. There are only 2 things that will change my plan and they're both revolving around our fathers whose health is rapidly fading, my dad is in hospice and my FIL could leave us at any time.
