I did but I'm in an area that had around 85% of the eclipse. I thought it would get a little darker out but it was still strange with so much less light beaming down. I didn't notice a temperature change either.
75% where I live and I definitely noticed a temperature change. I was outside in direct sunlight so that may have been the difference. Pretty cool to watch. I've learned that in another 7 years my area will have a 100% coverage eclipse and I can hardly wait to experience the difference so soon.
