I'm not a S&W guy, I haven't had a chance to play it, but, I do love the OSR. So I'll end up doing a cool map for the day that will be useable in pretty much any game. DCC ignited my use of old school ink again, as you've seen with my Clearspring town and The Light From Below DCC RPG game I've run.
So for a free map for any genre, but especially for OSR. Check back after Tax Day.
