1) Blame Mr Teddy Roosevelt for any deer problems. He decided that it was a good idea to put a 10$ bounty on every timber wolf in the nation. The timber wolves were nearly wiped out, and in the process the deer population exploded. Good work, TDR! Next time please do not skip biology and ecosystems 101 before heading to the Oval Office
2) I was once the victim of a horrific Jurassic Park style deer ambush in the middle of a residential community. Several deer popped out onto the road in front of my moms car as she and me and our corgi were driving one day. I shouted "Deer!" and we stopped... and that's when they struck... not from the front, but from the side--
the other deer you didn't even know was there!
We heard this Ka-thunk and I looked off to my right just in time to see a deer descending from the roof of the car. That's right, a deer jumped on the roof of the car.
My corgi was unfazed by all this though

Clever girl..
