We drive to S Texas every year, starting by going through Wisconsin.
There are a couple of beer places in north Arkansas (Fayetteville) but most of Arkansas along I40 and I30 seem to be dry counties besides! So, I think Arkansas is a bit of a beer wasteland, sorry to say. We always brought our own beer in a cooler in our car for overnight stays in Arkansas. I do love the BBQ and fried catfish around Hope, AR!
