The party embarks on an overland journey. But where will they pass the nights? Do you have several campsites ready so you don't have to simply say, "At the end of the day, you make camp and night passes"?
The tables of this document allow you to quickly improvise a campsite. With a few d12 rolls (a common die that needs more uses!) you'll have a basic campsite setting, when it was last used, how plentiful water and fuel are, and ideas for as many occurrences (normal or unusual) as you feel appropriate.
See the preview for a couple of examples and the first two tables!
