Yeah! the surface is sheets or layers of shale type rock, like dinner plates on top of one another, extremely slippery. problem is if you get sideways, which is something you do your best not to, then it's a roll right to the bottom. An acquaintance of my Son rolled a 'Lux from about halfway up to the bottom, lucky he wasn't hurt, 'Lux wasn't so lucky though, Regards Frank.
