Go to the community page at Eclipse2017.org. Choose a state and then the city you want to check out. The site will you give the location, an interactive Google map (which doesn’t always work, just go directly to Google Maps and look up the city), an eclipse path map, the duration of totality, when the eclipse starts, and when totality starts. Simple.
