They have been joined by 7 enthusiastic members of the community that add to the depth of the organization.

Gretta Reischauer, Executive Director/Naturalist
Gretta Reischauer has been a naturalist for over 10 years. Not only has she helped her parents in many of their camping ventures, but was recently the Executive Director of a non-profit nature center in Des Moines, IA. There, she developed several environmental education programs to bring into the classroom. Other programs developed by her were: after-school science programs for "at-risk" middle school students; a community service/habitat enhancement work project for "Science Bound" high school students, adult continuing education classes and elderhostels. Gretta delivers most of the programs. 
Darci Bouchard, President

Bill Slinger, Vice President
Bill Slinger is a classroom Earth Science teacher for over 20 years who has been in Outdoor Education for the past 15 years. Bill has developed curriculum for middle school students in Astronomy, Geology and Archaeology at three camps. At each camp he also offered continuing credit courses for teachers in Astronomy and Geology that were very well received. These courses encouraged educators to teach with more of a hands-on philosophy to help those students who may not be textbook learners. Recently, he has supervised student teachers for Gustavus Adolphus College. Currently, he teaches Geology to elementary teachers at Minnesota State University at Mankato. Bill helps to develop and teach some of our programs. 
Sharron Slinger, Treasurer
Sharron Slinger was a classroom English, Drama and Spanish teacher for nearly 25 years, and is the administrative "glue" that keeps our organization together, taking care of finances, schedules, publicity, budgets and purchasing, registration, etc. She has been an administrative assistant at three outdoor education sites and has also been the Administrative Assistant for the Chaplain at Gustavus Adolphus College in Minnesota. She has also catered for large groups and has run camp kitchens for several years.

Mark Reischauer, Director
Mark Reischauer is a master carpenter for 13 years who now is in charge of bidding and purchasing for construction sites. In this position he has had to deal with customer relations and crew. He was raised on a farm and is very good at running and fixing heavy machinery, general maintenance, landscaping and hard labor. He is also an amateur Astronomy buff and has constructed challenge course obstacles at three camps. Like Sharron, he is a very important member to help keep the dreamers in the family closer to reality.

They have experience in setting tables, mowing and yard care, and helping on hikes or at our festivals for the public.

All are very personable and can easily befriend the campers, especially those who seem apprehensive or out of the main group.
