I guess we got lucky. Just got back from western Kentucky, about 20 miles from the greatest duration, and we had beautiful skies. There were some light fluffy outer clouds, but overhead was very clear. Got to see the entire event on a deserted rocky lake shore that was only accessible by hiking in. There was only one other person there and he kayaked in! It was pretty freakin incredible! Except for the mid 90 temps and high humidity, which was a KILLER backpacking in, it couldn't have turned out any better! The total eclipse period was impressive to say the least. You just can't describe it, but having a 360* red sky sunset is pretty amazing.
