It's the original guy, Rudy Reavis. I was surfing with a kid and ran across this. Tim Walker and I tied at 7-1.5 that night in Princeton, and had to have a jump off. We both missed 3 attempts at 7-3.25. T&F news reported that I had come the closest on two attempts. Tim cleared 7-1 again, while nicked the bar off, which gave Tim the win.
But, I post to respond to the original question. I cannot say who was from the Boston area, but I can tell you that when I won the 1974 Penn Relays Boys HJ, it was reported to have been the most competitive contest ever at that time. I believe 6-4 earned an invite to Penn.
We had perfect weather, 80 degrees and sunshine, that worked for everyone. A total of 18 kids out of a field of about 45 cleared 6-8 or higher that day. It was extraodinary. I was jumping last in the entire field because I had qualified and outdoor mark just a week prior to. Going last worked to my advantage. After watching 17 guys miss their first attempt at 6-10, I saw an opportunity, got adrenalined up, cleared it, and won. No one else jumped higher that day. Thanks for listening.
