Does anyone play in an exploration-based campaign featuring mapping of the wilderness and underground sites (either on hex/graph paper or freehand)? Or are you in a "let the battlemat handle the mapping" sort of game?
We don't use battlemaps, per se. Typically, I use these big sheets of graph paper that measure about 2' x 2.5'. This, I tack onto a large cork board that we throw over the kitchen table.
Tacks have colored dots on them and represent characters. I draw on the graph paper with a black magic marker. Sometimes, I'll have pre-made maps. Sometimes, I draw as I go.
It's not unlike the old pencil and 8.5" x 11" graph paper from my 1E AD&D days--except bigger.
I usually do all the drawing--just out to the characters' line of sight. I work of a master map, translating it to the big map as the characters move.
My campaign is a mixture of both. I've created a huge sandbox for the players to explore. As we go, and the gaming years pass, I keep adding to the map as the players discover things. The PCs might hear a rumor and go exploring. Or, I might just put something in their path as they're moving from one part of the map to the other.
I might put "adventure path" style adventures into the campaign, but if I did, I'd just adjust the adventure so that the locations fit where I wanted them to on the big local map I've made (over 2,000 square miles).
