I still haven't gotten over my fear of RR. JanT will probably know which ones I'm talking about to: In Tempe on Kyrene just past Eliot I think. Same thing, crosses the road at an angle and I was being careful but I hit a bump which dropped the tire right down into the tracks and I went Endo. A fellow biker tried to stop and help me and he did exactly the same thing. I damaged my thumb pretty badly that day not to mention all the other various and minor scrapes and bruises. My riding buddy set a route a few weeks back that included lots of RR tracks to help my overcome my fear of them. I'm still a nervous nelly but at least I don't panic now when I see them. Good luck to your daughter.
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
