Hi I just found out that my brother who lives in SanFrancisco, was on a ride with a group of people and apparently he was going downhill and fishtailed and missed the corner and hit a guard rail. I heard he was airlifted to a Hospital in Walnut Creek. I was just wondering if any one was on that ride with him who could give me some more information about what happened. I am in Seattle and am hearing things second hand, so if anyone has any more info I'd apreciate hearing about it. Thanks so much. Be safe. Thanks
