I have a fall back plan, let's call it plan C.
I'll post it when we get there.
Here's the info for My house vs. Spring City TN.
There's no way to format this correctly that I know of here; my bet it to paste it into notepad, and it should be right, unless the site strips spaces.
Short version of the data:
My place sees totality. We get 1m 56.9s of total solar eclipse.
If we drive to Spring city, that gets a more centered totality that lasts 2m 39.0s of total solar eclipse.
The very best possible is 2 minutes 41 seconds, somewhere in Illinois, above Kentucky.

If someone knows how to format this into a table here, I'd love to see how.
