The streets of this city are very broken and it is up to you to repair them. In order to do this you will have to carefully drive a bobcat and park it with great skill. First collect the materials you need and take them to where the street needs repairing. While the bobcat is in function, it will move very slow, so watch out for the traffic. Make sure you complete your mission without destroying your vehicle and before the time runs out. Have a lot of fun playing Bobcat Parking!
