I am completely new at this. I'll be ordering my first hammock soon, a DangerBird from Dream Hammock. The first trip I'll take it on will be in Ohio in June. What sleeping bag temp rating should I look into? I have been told that it is colder to sleep in a hammock than a tent would be. I was mostly worried about the posibility of having some nasty weather and having it cool down on me more than expected.
