When I was still in college, one of the busiest nights of the year was actually Christmas day because all the college kids were back home visiting their parents and would go out to see all their old high school friends who were also back visiting from college. I don't know if it is still a thing now but it was a really stupid day to do that also and I guess the police just let everyone get a pass on drink driving that night. A little "don't crash and we wont interfere" sort of gift from the boys in blue.
