I did the standard trick of a pin-hole projector, and I looked at the sunlight that passed through the trees (which gives the cool, 100's of cresents pattern on the ground).
Then I looked up at the sun. AAARGGHHH!!!! I'VE BEEN BLINDED!!!!! Okay, I wasn't actually blinded, nor was my vision impaired in any manner.
Anyway, the partly cloudy weather is great for eclipse viewing. As the sun starts to pass behind the clouds, there is a short period during which the clouds block enough light that you can look at the sun and see the crescent shape of the eclipse. I even took a couple of pictures, although with my 80mm lense the crescent is pretty small. And I didn't look at it very long - just in case
When the sun is fully out from behind the clouds, it was a bit strange outside. It wasn't bright enough for 1 PM, and the sun has no warming effect (it was about 90% eclipsed here). However, it was still much too bright too look directly at the sun.
