One thing I learned in the Army, when navigating, was that people tend to wander towards their dominant hand. to offset that, we always used the compass in our weak hand. It actually seemed to work, at least to me. Sort of like minor auto-corrections.
i seem to recall reading somewhere that when trying to walk in a straight line in a forest that - if you were right handed, for example - you should always pass to the left of a tree. and to the right side if you were left handed.
any others recall this?
