Thankfully I can usually stick to the main roads, but there are some streets around here (Twin Cities) where you really have to drive carefully, especially at night, or you run the risk of having a bunch of deer charging straight at your car. Most of the time you can just stop driving and they'll meander across the road in peace, but sometimes they get the crazy idea in mind of making a mad dash just as a car is going past, and end up crashing right into the side of the vehicle.
