I once hit a groundhog on a Ducati Superbike during a race in 1998 at over 100 MPH. It just went "thump" and I kept going. My seat had a new crease in it, but I found that groundhogs are "soft". Had I tried to miss it, I would have crashed big-time.
Hey Tim,
We were roadracing in an endurance race in Monterrey Mexico when goats wondered on the track. Luckily no one hit one and they stopped the race long enough to chase them away !!
