day 25, mile, Hwy 90, 15 miles east of Marathon, TX

I can't beleive we've only just now started sleeping in drainage tunnels under roads. But, now that we have, I feel so smart that i'm afraid my bulging cranium will no longer be able to support it's own weight and that, in the morning, i'll wake up and find that it's caved in and begun to mildew.
