After seeing the discussion about the cheap down bag at Walmart, I decided to give it a try as an inexpensive TQ. The online specilal had the sleeping bag for $69.99, or the bag plus a 26" pad for $69.00.
The package arrive yesterday and looked promising. It packs incredibly light and small, but doesn't feel like there's much there, so I decided to try it out in the backyard last night to see if it was warmer than it looks. Learned two things:
First, pick a cooler night. Low last night was 67F, so I didn't even use insulation, and second and most importantly:
Remember when your sprinklers are programmed to come on!
We'll try again after everything dries out!
