"How far is that," said the agent.
"Oh, about 1500 miles one-way."
The agent said, "Oh, wow, so that's, what, one full day of driving, right?"
Either this fellow has never actually driven cross-country or else he doesn't need food, sleep, or restroom breaks. Heck, we didn't even allow that much distance in my long-haul truckload modeling with team drivers, where one driver sleeps in the back of the truck while the other one keeps moving on.
I made the San Antonio trip plans based on roughly 350 miles/day. Yes, I could probably go more than that (and we will on a couple of the days). But I don't want to spend 16 hours/day driving, and I simply can't drive without a break every couple of hours. I'm getting old and cranky about this.
