As the event gets closer traffic looks to be a big concern especially near the public viewing areas. Those aiming for Kentucky found this:https://www.facebook.com/solareclipsefranklinky2017/
Check out the link to the Drive-In, paved parking with a snack bar, restrooms and right off the interstate. Probably not going to be the most photographic area sitting in a parking lot, but easy access and everyone will be looking up at the sky.
The Race track up the road has a huge parking lot and grass infield, but they make no mention of events for visitors on Aug 21st.
Weather permitting, this looks like my current destination.
