I hit my tee shot and it headed for an area that is basically full of unplayable lies and is not marked as a hazard.The cart path cuts through this area. I found and identified my ball, which was under a bush (unplayable) on left side of cart path (closest to fairway and hole).My nearest point of relief within two club lengths would be another unplayable lie or on the cart path. In keeping the spot where my ball lies between me and the hole, going back on that line would put me on the other side of cart path also in the junk with another unplayable lie, except for a very small patch of clear dirt if I could happen to get lucky and have the ball stop there. If I could, I'd be standing on the cart path and nearest point would be in the junk again. Is best (and probably only) option here to go back to the tee?
