If you are from Utah like I am, you don't encounter a lot of toll booths in your day to day driving.
But if your are from an area where toll booths are common place, well....
While visiting Florida driving on the local highways and biways, we encountered many toll booths. Its a bit annoying. I can't imagine having to always be sure that I have enough money for toll booths. Can you imagine having to say,
"Whoops,I don't have money for the toll booths so..."
At one toll booth we had our money all ready to pay, but the toll booth guy told us the car in front of us had paid our toll. It wasn't until we drove away in a bit of shock that we realized that we should have paid for the car behind us. How awesome would it have been to pay for the car behind you, and them paying for the car behind them, and so on.... I think that would have been awesome, but we didn't think of it fast enough. (maybe that was what the person ahead of us had in mind and we went and ruined it) Oh well, next time we travel we will be sure to pay for the car behind us when we come to a toll. We could use more simple anonymous kindness in the world, don't you think ;D
