What are some games to play on a bus trip?

"Road Sign ABC" is one game to play on a bus trip. The game is played by finding the letters of the alphabet on road signs. Only one letter can be used per sign, and the game ends when the first person finds all 26 letters.

Another game is called the "Name Game." This game is played when a person picks the name of a country or a town. The next person then has to pick the name of a country or a town using the last letter of the name given before them. No two names can be used more than once. This can also be played using celebrity names.
