It looked like it was going to be cloudy in my neck of the woods near Lincoln so I went out west 90 miles to around Grand Island, Nebraska and had fairly clear skies the whole time. I had been trying to find #12 welders glass for a week, but everything was sold out (I waited too long), but the morning of, I went and found a welding shop and they had #11, so I snatched it up. The crazy thing is, his credit card machine was down so thank goodness I had cash.
Almost everything from that point worked flawlessly. There were a few hiccups with my focusing, but they weren't too bad. The only thing that didn't go as planned was the live video of the sky darkening. The camera stopped after 12 minutes for whatever reason, but it was just after the sky got dark so at least we saw that.
Overall, I couldn't be happier with how this video turned out. I think the totality video was worth it all by itself. Everything else was just bonus.
