OCCA and Walk leader Margret Grebowicz are thrilled at how popular this series has become. Again, this walk will add and reinforce knowledge for participants who came on any of the first three walks but is also open to first-time participants. Participants should dress for a walk through the woods, wearing long pants and shoes you don't mind getting muddy. Margret also asks that everyone bring a small knife and paper bag for collecting. The location will be emailed to registered participants.
