Brian Nelson, known to runners in Sioux Falls as the Hockey Guy to all trail users due to his constant presence on the trails with roller blades and often a hockey stick. A lifetime of running and chasing his wife and son to great running accomplishments makes him one of theme of the most knowledgeable track minds I have had the joy of to meet. He has also documented SDSU track and cross meets on YouTube, see link below.
