I think the best strip in the state to watch the eclipse would be John Harris Field. It sits up on a bluff that overlooks the country side for miles and miles. You’d be able to see the shadow of the moon moving over the earth. It’s really close to the centerline of the path of totality. Totality will last 4 minutes an 9 seconds here. There’s not really any amenities for camping here and I’d contact the owner first if you’re planning on camping.

Petit Jean will be even closer to the centerline with 4 minutes and 15 seconds of totality. There’s actually a real nice campground at the south end near the lake. The sites have water and electricity. There’s also a bathhouse with restrooms and I think showers as well.
Richland Creek is a great place to camp at. The RAF recently build a shelter at the main camping area that has a picnic table, BBQ, and firepit that’s always stocked with firewood. There’s also a pit toilet that has solar powered lights and one 110v outlet you could use to recharge your things. Totality will be 3 minutes and 22 seconds here.
Byrd’s is a great place to camp as well, and has a nice restaurant overlooking the Mulberry River. But if you’re flying all this way to see the eclipse I’d go to one of the other options (Byrd’s would make a good base camp though). Totality here lasts only a minute and 39 seconds.
