I love a good geography quiz! The United States has 23 states that border the Atlantic Ocean, the Pacific Ocean, or the Gulf of Mexico. In this quiz from mental_floss, you are challenged to name all 23 in three minutes. I did it with a half-minute to spare! And I would have done it faster if I could type as well as I read a mental map. Link
I agree that it is too much time. It shouldn't be that difficult to name them. Maybe in a minute. Then, you wouldn't really have time to think.
On a side note, I had difficulty spelling some of those states. ha ha. Geography--I'm not bad; Spelling--forget about it.
