I shouldn't pick up anything else, but I've been thinking about starting a primitive cartography club. Folks could use means and methods similar to what was used in the 18th and 19th centuries to make maps for fun, education, and decoration. Maybe have competitions to locate buried treasure or something. Good exercise!
