[at-l] Airbed insulation?

[Linda Patton]

If one were using an airbed on the ground in a tent in, say, mid-October 
in, say, West Virginia, would one need some kind of insulation under or 
over the airbed?  If so, what kind?  Would a wool Army blanket under it 
and a comforter over it (and under the sleeping bag) work?  It's twin 
size, so I don't think a windshield sun reflector would be large enough.

And...anyone gonna be camped at Pipestem State Park by Thursday 10/14 and 
willing to help me set up a humongous stand-up-in tent I just bought?  It 
even has a screened porch!  Doesn't exactly fit in the ultra-light category.  
It's a Touron Tent for sure.  My first major concession to old age.  Guess 
it's all downhill from here, huh?  ;-)  ~~ eArThworm
