Happy Monday to all you drivers out there. We’ll get the week going with some trivia about how things used to move across this great country.

Back in 1860, there were about 157 Pony Express stations (their equivalent of terminals) that were roughly 10 miles apart. Care to take a guess why 10 miles was the magic number?

Post your best guess here. Then have a safe and happy Monday! We’ll post the answer here later today.
