I think it is a necessity that the residents or anybody for that matter that drives on 25A needs to be aware of the deer population.
I never thought about a deer running out in front of my car in the middle of a populated area as Kings Park. I have a summer home in the Poconos and I am always very careful when I drive on the roads because of the deer all over the place.
Just last week, I was driving home, with a brand new car that I just drove out of a dealership just one hour prior, when a deer ran across the road, right in front of the Jewish Center on 25A (main street), hit the front of my car and needless to say caused damage to the the front end of my car. I was lucky no one in the car was hurt, but I believe there should be signs posted to alert people of deer crossings. It has now made me very aware to look in the open areas to see if there are deer present.
A gentleman who works in the parks department was right there at the time and said that this was the 3rd hit in the last three months or so and that there are an abundance of deer in the psychiatric area.
