Couple of options
While Lerch is gone you should go over to his house and get the Hall Runner. If he doeesn't have one then just go into the living room and cut a 7 foot by three foot rectangle out of his carpet.
Second option is a closed cell foam sleeping bag pad. Thermarest makes one that accordion folds. Disadvantage is that sharp sticks etc will poke through it. Advantage is it is very light. Other thing is it doesn't get soggy like cloth. In case it is not obvius, I hate sitting or laying on wet ground (or cold for that matter). Here is one of mine on the backpack.
Here it is set up for a Potomac River elk [img]/ubbthreads/images/graemlins/grin.gif[/img]
