We were just shy of 80% here. Definitely dimmed quite a bit, and I kept checking outside the window to see if it was clouds or the eclipse (there were defnitive shadows on the ground, so it was definitely the eclipse).
A lot of people were disappointed in that they were expecting it to be darker. That's the thing - it doesn't get really dark, even 99%, except for those in the path of totality. As I said earlier, in 2024 Detroit will get 99% of totality. I really want to go out to my wife's family's place in northeast Ohio (about 4 hours from where I live) to experience the total eclipse. Plus I absolutely love that part of her family, and, considering how my wife's aunt liked my Facebook comment about them having the total eclipse in 2024, I'm pretty sure we already have the invite.
