Right around 5 miles into the ride I was back a bit with Sylvia when I heard Char calling me. Vivian had stacked it pretty bad. In her words she grabbed too much front brake on a rocky section. Her front tire washed out and she tore open her chin which was bleeding a lot along with some huge trail rash on the insides of her elbows, one knee, and stomach. We spent some time calming her down and cleaning her up as best we could (and also used some of our water in this effort as well) and then set out.
