Back in the 1970 's a lady friend and I decided to hike Overlook on a Summer's eve. Once on top we encountered a severe thunderstorm. Fortunately we were close to the rangers cabin , and were able to wait it out. It was getting dark and the road was steaming from the hot humid weather that day.As we proceded down the road by the hotel,I noticed not one but several good sized rattlers were warming on the jeep trail.With not much day light left,and my imagination running wild as to what might happened next,we made what I would consider my best time ever off of Overlook Mtn..I think you would almost have to step on one to get a bite.But without a flash light or a headlamp,that's what I was afraid of.They don't want anything to do with humans,just take some precautions.
