My Dear James,

I fear you have been doing too much credit card/motel camping as of late.

Ground cloths are made to: COVER THE GROUND. (Amazing, huh?)

The ground may be:
wet or damp
full of creepy crawlies
covered with abrasive rocks

It is these things, my dear fellow, against which one must fortify oneself with a...
GROUNDCLOTH! Not to do so is simply ungentlemanly/ungentlewomanly. Egad! Not using a groundcloth - SO uncouth. One must alwaus be couth when in the wilds
