If you are between those two blue lines you'll be in the path of totality. Outside that path you'll see a partial eclipse. I anticipate making a trek to the Kentucky/Tennessee area on August 21, 2017. No way I'm going to miss this opportunity!!! Looking at the map you need to be in the correct place at the correct time. Make a mistake on the location and you have no time to move. The path of the Moon's shadow on Earth moves very quickly. The total eclipse will last less than 3 minutes at any given location! Thirty eight years since the last one and this one only lasts 3 minutes! Wow!
If you're anywhere near that path, take time to maneuver your way into it because it will be well worth it!!!
