My buddies and I would hit up the desert at night and go 4 wheeling on the trails. This one night we had stopped for a break and this guy rolls up on us. He asks us if he can join us and we say sure. We continue riding and I was second to last, with him being the last one. We were pretty familiar with the trails so I kept looking back checking in on him not knowing how familiar he was or experienced rider he was. As we’re approaching the hill that over looks most of the area I look back and he’s gone. I flag my buddies down and we go back to look for him. Nothing. We go up the hill, kill our engines and listen for his bike or look for his lights. It was pitch black and not a sound. From the hill I’m sure you could see for a few miles, but there was no trace of him. We looked for him or his bike till about 3am and we’re unsuccessful. It still kinda bugs me that a guy just vanished like that. I hope nothing happened to the dude.
