In my 12 mile drive to Nipissing it is common to count 60 deer in the early morning or evening.
Most times it's not the one you see that will get you. Pay attention to the one that you can't see. Where there is one, there are usually more.
I have so far avoided hitting one, must be my finely honed hunting skills . Seriously though, I have slowed my driving speeds down, often below the limit especially in the areas where they are more prevalent.
