I couldn't find anything on this with a search....
Some people use miniatures, either on a hex/grid or just to represent a vague idea of where their character stands.
A group I was in used yard sticks to show movement of their miniatures; no grid required. It was kind of weird. I show up and everyone has a yard stick in their hand. They said "Every inch equals 5 ft. This way, no one has to get up and squint over the table to see positions." I thought it was a bit odd, but they were pretty keen on it.
Maybe I'm "old school", but I always liked hex's/grids...
Anyway, how does everyone else handle movement/position?
