I worked with Peter in the early 90's. Surfed with him on a few occasions at Sharks. I have some old surf video that has him riding some pretty serious beachbreak - stuff I'd not care to go out in. He was a character.
Peter was also a master of the drop knee cutback!
Late, mid morning one day in 1963-64, at Doheney, Peter jumped up and demonstrated the DKC while Kevin Platt, Nat young and I observed and lapped it up - we were absorbing real 'hot dog', California style!
He demonstrated and we discussed with him who, how, what, where and when!
I adopted what Peter showed us, as did Nat. I won a world contest with Peter's cutback (not Phil's as per the poison pen of John Witzig).
Nat won numerous modern longboard world titles with exactly the same drop knee!
The essence of Peter's DKC was a crucifix upper body, balancing over a compressed, telemark style leg arrangement.
To this day I can still feel Peter's enthusiasm washing over me/us - it was the genesis for the next step we were to take into history.
Thank you Peter - thank you all the generous California people of his time!
