First head East until the road dead ends. Then turn right, and then left, at the next turning. Then take the second left and look for the arrow along this road. As there is a real emergency here you'll have to gun the engine hard to reach Lucky. Then turn around and head back towards the motel you started at, but instead, keep going west until you reach the area with lots turnings. Here you can consult the map to find the arrow but you'll have to be quick, the timer is strict here too. If you get lost consult the map!
