When it comes to storing a fishing rod on a car, there are a few options. The most popular and convenient way is to use a fishing rod rack. Fishing rod racks can be mounted on the roof, trunk, or even the door of your car. They vary in size and price, so you can find one that fits both your car and budget. Another option for storing a fishing rod on a car is to use an old tennis racket case or PVC pipe. If you don't have either of these items, you can always make your own! Simply cut a length of PVC pipe to fit your fishing rod and then drill holes in the top and bottom. This will allow you to thread rope or bungee cord through the holes and secure your fishing rod in place.
