I envy those who will be in the path. I experienced the 1994 eclipse. There is an amazing eeriness in the ambient light quality in the environment. All the light values change in your visual surroundings not like twilight. Based on these 20 year memories, I'd suggest bring a second camera because there may be some cityscape/landscape opportunities too. I think there was an interesting phenomena gazing through the tree leaves prior to the full eclipse. It was seeing hundreds of suns. Hopefully my memories serve me right. Get some great shots to share here.
