My first major trip in my car was NY to St. Paul on my way out to school. I did it on a saturday night 9pm into a sunday (arrived at 12pm CST) in about 16 hours of driving 15 after the time difference i basically drove 90-105 the entire way and luckily did not get pulled over anywhere on 80, 90, or 94. I believe I encountered radar 2 times that night. Once in NJ around 10 and once in Ohio around 3am. I am about to invest in a Laser Jammer, but I was just curious (since I do most of my long trips at night) about laser's use/ effectiveness in the dark? Do more officers not use laser at night and only radar?
