Stopping for iced coffee every 20 miles? I quit caffeine long ago but even then I wasn't stopping every 20 miles for anything, much less an overpriced espresso or iced coffee. I don't even stop on metric centuries unless I have to piss. Quitting caffeine improved my life even more than quitting alcohol 15 some odd years ago, by the way. Best thing I ever did, I've slept like a baby at night ever since.
