We started a trivia thread over at another forum and it has been a lot of fun.
Here are the ground rules. It starts with one question. The first reply with the right answer gets the floor for a new question. It continues like that unless, A) the person who has the floor doesn't ask a new question, or B) no one gets the correct answer. In that case, the person with the floor asks a new question. No more than one question on the floor at a time, and discussion/clarification is welcome until the floor is taken over by a new question.
See this thread for an example of how it goes: http://grassrootsmotorsports.com/for...ia/1454/page1/
First question: In the 1952 Indy 500, what type of fuel was burned in the record-setting pole-position #28 car? Hint: it won pole position by a full 4 mph over the second-place Ferrari
