Ah, you young people. I remember when gas went up from $0.249 to $0.259 per gallon. By the I started driving you had to drive two more miles to find a gas station with gas at $0.309.
But you know, a credit card is a whole lot easier to carry than it was to tow a trailer a bunch of those stone discs with a hole in them! Those $50 stones were HEAVY!!
