How do you all keep your charts? How old a chart would
you consider
using when visiting a relatively unfmiliar... or
completely
unfamiliar... area?

I would not use an old chart at all in an unfamiliar area.
Sandbanks move,
buoys are shifted, wrecks appear, lights change
characteristics, etc etc.
Forget old charts for navigation. Frame them and hang them
on the wall if
you like. But on your boat have new charts or ones that
have been regularly
updated from 'Notices to Mariners' (or your local
equivlent) either by
yourself or by returning your charts to a chart agent for
correction up to
date.
Apart from being a danger to yourself and others your
insurance may be
deemed invalid on grounds that you were negligent if you
knowingly go to sea
with out-of-date charts.
