I believe this is a GoPro on my buddie's helmet. The non fish eye lense along with the chest mount perspective actually shows a bit of the abuse taken when riding Pat's Trail.
There's a hundred videos of this same trail on youtube but none of them show the depth and contours of the rocky trail terrain like this one. And atleast you can tell it's a hill, with the helmet top fisheyes you really can't.
