Just got back from a trip to Shawnee NF to do some herpin'. I convinced my dad to get a GT UL, and he tried it out last night. He's a believer now. He slept for 12 hours! I pitched my new Guide Gear 12x12 tarp over both of our hammocks as pictured. Thanks to dejoha for the great no-sew DIY PLUQ instructions; I used it last night along with a thin pad and it felt like an oven at about 40 degrees.
Not much luck with herps, but there's another hammocker in the crowd now.
