Carroll was a very good competitive surfer. He won the United States Surfing Championship held at HB I think 4 times. That was a big time event for that era.
I think he won the ISC championships two or three times too.
I think he has said he was the first person to be sponsored by a company and be paid to surf regardless of how he finished in a contest.
I think the most impressive thing he has done is that he has managed to go through life without getting a real job. He currently writes a fun to read column each week for the OC Register where he discusses various surf related issues of the past and present and tells wise crack jokes. Another day each week the OC Register has a column where he answers surf related questions. He announces local surf contests and runs surf schools.
