Dont know what the rabbits are like over there...
We tend to have the ocasional "camacazi" rabit. Ive had 2 this year that did this...You see them in the middle of the road and you hear a thud. Just figure I ran over them...but no...the little b@st@rds jumped. Both times i had to wash blood and fur from the grill of my truck :-/
No one knows why they do that but there has been several others report this happening...
