Just picked up on this thread and noticed the reference to Canada - the place where you have to know the range at which you can tell the difference between a moose and a reindeer. Might have been handy in this situation!
Personally, I'd have stopped at 45 deg to the grass with my hand on the throttle waiting to see where his roll out would end. But then I havn't seen the grass. (or the approach lights concealed in it)
