There's not much between Huntsville and Birmingham, except somewhere near an hour and a half of scenery that can be compressed into approximately three minutes of equally unexciting viewing:

"Hmm."
"Look. Trees."
"More trees."
"Is there anything else to see?"
"More trees, I think."
"Are we there yet?"
"Given that we left five minutes ago, and it takes nearly an hour and a half to get there, I think that highly unlikely."

It's a pity, really; Alabama seems to be missing some of the out-and-out oddness that is the freeway scenery in Arkansas. Anyone who has driven I-30 has encountered one of the most famous (and enduring) billboards in central Arkansas:

Enormous capital letters, the billboard equivalent of a shout:

"WARNING! PREPARE TO MEET GOD!"
