Yeah, just black ones around here and I haven't even seen one yet, except on TV They had the thing on the run. My hammock is gray. I wanted to be stealthy but my fly is wally world cheap nylon green. You can see it thru thick forest. I always sleep like a baby anyway. I think the sutle gastric noises and fumes should keep them away. It'sjust my way of marking my teritory as any animal would do. <img src="/forums/images/graemlins/grin.gif" alt="" />
