I've been wondering whether or not it's actually needed to bring along ground cloths for tents. This may be the very last bit of Scouting in me(where we always carried ground clothes and gi-normous Coleman stoves) but for the life of me I'm having a hard time picturing tenting without a ground cloth.
Wouldn't that more easily damage the tent floor if I left it at home? Or, as Jason Klass suggests, do hikers cycle through tents quick enough that the benefits of ground cloths never outweigh, well, the weight?
