I'm wondering if I'm crazy for attempting a Mon am fly-in (award ticket of course) to catch the eclipse...

Both MCI and BNA airports appear to have parking garages with an open upper deck that would provide a clear skyward view. Then right back onto a return flight. Could do CAE or CHS too, but forecast isn't looking great.

Pro: I can switch cities last minute if the weather forecast goes bad.
Con: IRROPs.

Or I have a Sun hotel room north of Nashville and a Sun-Mon car rental that I can use.

Pro: No morning stress. Can potentially use car to dodge clouds.
Con: Can't switch cities last minute for weather. And (minor) $$$ of hotel+car.
