This is a 4x4 Trail? So far, its nothing I wouldn't drive over in a rental car. As we look across a small gully to our left we see Mad Mouse Trail coming back down the side of a hill towards us. It looks steep and tilted from here, but looks can be deceiving. Onward we journey until we hear the sound of gunfire. I'm not talking pop-guns or pea shooters, and we're heading right for the source.
