I copied tncamper, I think? I saw a post this summer where he camped on his business trip. I had a meeting at corporate office in Beaumont, so I went to Lumberton and camped at Village Creek State Park. There were 3 RV's and NO primitive campers. Sweet little park, about a half mile hike into sites and had the whole place to myself. Nice camp fire and a little sipping whiskey. Perfect opportunity to test my rigs limits. I have an HG 20* 3/4 phoenix and a HG 40* Burrow. My last test left me a little chilly in high 30's. This test it got down to 32*, I added a small piece of reflectix under my feet and wore some really large loose socks as suggested here. It made all the difference and I can say I honestly was warm under the quilt. Woke up at sunrise, made a pot of coffee, packed up, hit the hot showers and meetings all day. I may just have to do this again. Can't wait to hear about firewood on my expense report! Still saved the company about $62 for the night.
