Liam looks at the map and thinks for a bit."That certainly does seem like a good plan, but we should probably invest in a few tents. Even if we weren't going to go into the forest, the nearest cave seems over a day's walk away. The way I see it we should go into the forest, head east from there, and If we don't find anything in the forest we set up camp and go to the caves tommorrow."
Maybe not applicable in this case for some reason, but according to the PHB, a human with a light load can walk 24 miles a day, and as a Boy Scout I feel I'm qualified to say that even that is pushing it.
