Wylde Roly Poly crash today - Lost Helmet

Hi all,

A guy named Michael came off on the Roly Poly today at Wylde MTB park.
I suspect his shoulder may have dislocated and popped back in.
We helped him back to the car park where somebody came to meet him and take him and his car home.

I wanted to post this because he left his Helmet in my car as we were taking him and his bike back.
I'm fairly sure he said he was from the North Shore, so I thought I would try my luck on here.

He rides a yellow 27.5 inch dually, can't remember which brand.
If any of you happen to know him please put him in touch with me.

Thanks, Zeb
