I'm wondering how harrowing it would be to have one or two drivers drive from the approximate location of Little Rock either north or south into the eclipse path. Maybe we can find a field, or even a backyard, with people who don't mind hosting some nerds overnight.

Another thing which I haven't seen mentioned: Won't we need special viewing devices to keep ourselves from getting sun damage on our eyes? Maybe we can get a screen at an angle and put a tiny hole in some very thin paper? Or a camera with a sunglasses-type lens?

I know nothing about this stuff, so maybe I'm sounding like an idiot. (yes, I'm very good at sounding like an idiot, though I'd defend some of my ideas more vigorously than the others)

Edit: Should we be concerned about people who view the eclipse in an unpleasant "Jesus freaky" sort of way? I enjoy Googling prophecy about that type stuff, but I can put it aside. No idea how likely it is that people would go to the eclipse to tell people about the end of the world, not that that would be bad in and of itself. Maybe stay away from the Koolaid and drinks opened for you by random people?

The pin hole projection is the cheapest and easiest device for safe viewing. For safe direct viewing, search "eclipse glasses", (even though most are metalized plastic film.)

For photography, without burning the camera sensor, see here, or similar:

Take a deep breath before looking at prices.

You can order inexpensive eye protection from www.eclipse2017.org

The primary school I was attending at that time handed out free eye protecting for the (partial) solar eclipse of 1999 in the Netherlands (yeah, I'm still a young adult )

I have cut up those eclipse glasses and used duct tape to cover both lenses of my binoculars to look at the partial/annular eclipse in 2012. It works fine, but you must make absolutely certain that there are no cracks around the duct tape where unfiltered sunlight can get through and damage your eyesight. During totality, you can then rip off the filters for a spectacular view.

I researched a good chunk of the eclipse track on a drive last summer between Oregon and Nebraska. Eastern Oregon is a sweet spot for likelihood of clear skies, and Eastern Wyoming is as well. Mountainous areas, such as the Oregon Cascades and Blue Mountains, the Idaho Sawtooths and Lost River Range, the Wyoming Tetons and Wind River Range are tempting because of the spectacular scenery and the possibility of viewing the motion of the moon's shadow across the ground from a high vantage point, but the weather prospects are more iffy because of possible convective clouds. Of course, the Midwest and Southeast have a longer duration, but I would want to be sure that I could move if clouds threatened. Kansas City, St. Louis, and Nashville are all at least partially within the path, and you could easily drive to the center line the morning of the eclipse.

By the way, this eclipse is very similar geometrically to the August 1999 eclipse in Europe, being part of the same Saros cycle, wherein eclipses repeat with a period of 18 years, 10 and 1/3 days. Because of the 1/3 day, successive eclipses occur about 120 degrees west of each other.

... as well as geometrically similar to the one that crossed former USSR on July 31, 1981
I happened to be in Siberia then, at a place where it was almost total (99.1%).
In 1999, I was not in Europe but I heard a lot about that one.

To each 1/3 of earth, their own eclipse!

I had a real filter for my camera last time. I also had (and lost) a different filter that I used during a sunrise partial eclipse. I bought adapters to mate it to my 500mm Schmidt lens. I tried to get pictures of it rising over a well known lake.

WRT, taking off filters, I plan on taking an eye-patch to wear during the partial phase. Then pop it off during totality for a full dark adapted view.

I was in Cambridge at the time, specifically at the MS Research lab in the center of the city. We all climbed through a window on to a flat roof to get the best views of the ~98% eclipse.

I took along a pair of tripod-mounted 15x80 binoculars equipped with an aluminized mylar filter over one objective. Very fine views indeed of the photosphere and of a couple of smallish sunspots if memory serves.

I may "have to" relocate my eclipse viewing. So, one that has familial ties would like to join me, but only in their general area.
