This is not your normal wherigo cartridge! This cartridge puts you into the realms of interactive fiction. Those folks who remember the good old days of text adventures should get it :) 

This will take you into Grants Woods. It is a great trail.
The trails are open Dawn to Dusk ONLY.

You can download the cartridge HERE. You need a compatible player to play it.

You play the adventure. At each zone, the new zones you can reach will be displayed. Some choices may cause you to backtrack to find something else!

The help system will give you progressively better hints, up to a gimme so only use it if you get stuck.
