How to stay dryiest when it's raining?

I was talking to a college at work who explained that one often debated question that he had as a youth was whether it was better to run or walk when it was raining?
Do you walk, staying in the rain longer, or do you run and collect the same amount of water by running into it?
What do you think... well here is a short essay on the topic that I found, and it also agrees with my guess.
