I think I've seen 100% eclipses (or at least very close to 100%), but I don't quite quite remember where I was at the time or how long ago it was. I don't remember it being that big of a deal though and what we had here yesterday was more of a case of probably not even noticing it if you weren't looking at the sun with protective lenses. Hell, things get darker with just a typical summer cloud rolling over than during the eclipse.
