So yesterday all day I was greasing all the rails at sugar bowl and they had this down rail which I had slid no problem all day long. I tried a lipslide onto the down rail and the first three times I was fine. the fourth time I did it I was perfectly balanced and about 3/4's down the rail, i caught an edge and flew forward. As this happend I tweaked my knee a little bit and I think i did some meniscus damage.
So basically I was wondering how to prevent catching an edge on a rail and if this has happened to anyone else.
