I am planning on switching out my hammock this year for a poncho / tarp tent to lose some weight. I've been told to watch doing this because snakes tend to "look" for warm places to sleep and may be attracted to a warm body on the ground. Is this something to worry about or just a scare tactic? I'm hitting the section between the Susquehanna and Port Clinton this year in PA and from reading around, it sounds like most snake encounters came in this state. I'm not horribly worried about it, but don't really like the idea of having a snake try to get in my bag while I'm sleeping and accidently ticking him off.
