Group clinics are unique. We set a firm curriculum only after we have met with a client, so that we are on the same page with abilities and expectations. We learned this the hard way, years ago when we were doing clinics for the Women in the Outdoors events. It seems that the word "beginner" is a very subjective term.
Our trail design and construction projects are tailored to the needs of the land manager, with the understanding that we are volunteers, so our time of availability is premium.
