Arborist Jamboree in Victoria, BC

This past Saturday (Sept. 25) I had the opportunity to watch some pro arborists competing at Royal Roads in Victoria, BC. This was my first time watching the experts do their thing, and I was just amazed. I understood everything I saw them do, but the speed and athleticism demonstrated by these guys was more than I expected.
Was anybody else on this forum at the event, either watching or competing? One of the gentlemen hosting the event claimed that some of those attending were among "the top climbers in North America", but he didn't mention any names. Does anybody here know who these guys were?
