Vacay!

Tonight I'm driving "up North" to "the lake" to spend the week with my Aunt, Uncle, their kids, and their grandkids. I'm driving up kind of late and my Aunt told me to watch out for deer. So now I'm freaking out. How does one watch out for deer? It seems like one of those things where if a deer is going to run out into the middle of the road you're going to hit it. The end. I don't really see how watching out is going to help much. Maybe watching out means stress and be paranoid, in that case I'm totally watching out.
