There is a company in Loveland, Colorado called Road Kill Bingo that sells sets of bingo cards for traveling by car and recording the various items seen on the road. For example; they have tires, deer, skunk, rabbit, bird and other animals listed in the various blocks that you would mark off when seen. They also claim the games have been road tested to minimize the miles between bingos. They even go so far as suggesting you adjust the game for other countries, if some animals are less common. For example, they suggest you substitute “elephant” instead of “skunk”, while traveling in Africa.
