Recently, Pennsylvania reported 80,000 deer/motor vehicle collisions ... per year. And they are on the increase due to lack of predators and abundance of food (that means our farmers are not only feeding US!)
My sister in law in Round Hill, VA just mentioned a mass escape at a local bison farm! Gives you good reason to be thankful that they tested these in Europe against simulated moose!
Finally, if you want to seek revenge, the Smithsonian and National Zoo maintain a farm out near Front Royal to house their excess critters and raise food. The local deer have invaded and breed out of control. They open the area to hunter's groups to cull the population. Maybe you can find your attacker.
Good luck
