The dirt Road

You stop for a second after hearing a noise come from the forest off the road. then you see a tree the size of two men thick fly out of the tree line and two that were next to it fall to the ground. In between these two trees is a species of drake but you can't tell exactly what type at this distance. you see it's head turn toward you and you get a good look at the scales that fit like plate mail on the face of the monster. No matter what breed of drake the whole thing is going to be covered in scales. Now what do you do?
