Terrible news. I was around on that day. Him and his mates were doing some xc / trail ride around the woods and would sometime end up going down the transfer line at a good speed. Just to be clear there are no gaps or anything dangerous on that line just one table top in the middle. It’s probably the most popular line.
We tried to understand what happen but I think it simply was an unfortunate accident that had some very serious consequence. He went off track after a roller so maybe the high seat was an issue…
We must thank the paramedics and doctor that came down. Healing vibes to him.
