Most of my day yesterday was spent just trying to make the whole thing work.
It ends up that if we have to go through with that end of the issue, we leave town Thursday morning at 7 AM ET sharp, we arrive in Jax Thursday evening, after 12 1/2 hours of drive time. Friday, Mrs. Chairman gets to meet with the people selling the property, and has until 3 PM to wrap things up for that session. We must leave Jax by 4 PM. We then drive to Durham, NC (choosing that location is driven by our wonderful tax code and the desire to write off that leg of the trip, it is not the most beneficial timewise, but makes economic sense on the 1040), where we will arrive between 11 PM and 12 AM. Then we are out of Durham at 7 AM, to drive to West Memphis, AR. At that point, we are back on the previously planned schedule - which is far easier than those three days.
Barrels of good luck, Chairman! I think you'll be needing it on top of all your excellent planning.
