On further contemplation of a bovine deflecting bumper, I'm remembering what my insurance agent said about a deer encounter. "If you have a choice, do not swerve off the road but hit the deer straight on". Seems the insurance company will pay for any on-road encounter but not pay up if you swerve off the road and hit a tree or other obstacle.
The most debilitating collision with a large bovine creature is one that incapacitates your radiator. That's why I have the upper tube to help protect it. This one is marginal but a first line of defense.
