Man, that's tough. Sorry about your loss. That's one of the main reasons I could never pull the trigger on a bike. You could be the safest rider in the world and still have something like this happen. The fact that it happened on vacation is really heart breaking. I had a friend from high school (his name was Matt. He just recently died of cancer two months ago) who was on vacation with his family in Seattle a few years back. They were on those bicycle taxi things, you know, the vehicles with two seats in the rear and a guy peddling up front. Well anyway, Matt and his brother were riding in one, and their mom and dad were in another one in front of them. A freak accident happened in the one his parents were in, and it resulted the father being killed on the spot and the mother was left paralyzed from the waist down. I can't imagine ever witnessing something like that. Good luck to the members of your family as well as the family of the deceased.
