If you have bad allergies this may fire them up.

Watch as a tractor hits a tree and pollen falls from it. A cloud of pollen rains down as this tractor hits the tree and the operator of the tractor quickly backs away.

This makes me want to sneeze. Yes, this is what ends up on your car, house, etc as springtime arrives.

I hope that the person in the tractor doesn't have bad allergies because this certainly wouldn't help them.
