One of the things about motorbikes is the open-air feeling, without all that metal boxing you in from the outside world.
It's not always a good thing - like when you're being chased for a mile down a US highway by a massive angry elk.

It's mating season for elk bulls now, which probably explains the aggressive behaviour. Still, we wouldn't like to have been a cyclist out for a spin.
And just to put this in context – grown male elks weigh more than 300kg, and are about 5 feet tall by 8 feet wide. That's a lot of animal behind those antlers.
