Long road trips can be mind-numbing experiences. But there comes a time in every drive when finally, at long last, you get a physical marker of just how far you are from your destination. Way before we had GPS, we had highway distance signs.

When I was a kid, family trips up I-95 from D.C. to New York were broken up by those signs. On the way back down, somewhere just south of Baltimore, a sign let us know we were in the home stretch. Washington was just 30 miles away.
