1998 TRAIL DAZE
event in an effort to get the community more involved in the upkeep and conservation of their local recreational resources. As federal operating budgets were cut back, the U.S. Forest Service had been looking for ways to get the community more involved. The combination of these efforts grew into a successful advocacy program.
Before Chris King's Trail Daze, such volunteer projects lacked appeal and drew only small numbers of people. Trail Daze was a successful example of organization, leadership, food, and free stuff that took volunteer programs to a new level. It was responsible for improving many miles of trails throughout California's central coast and was used as a model for designing similar programs nation wide.
Each Trail Daze event started off with a complete continental breakfast and a bagged lunch providing fuel for the hard day's work. Volunteers were grouped into work parties and instructed on proper trail maintenance standards and techniques before they set out with their tools and hard hats. On the trail, the Mountain Bike Rangers lead the work parties providing trained expertise on the day's project. As the sun set, the volunteers were drawn back in by the lure of a hearty BBQ dinner and generous prize raffle featuring prizes donated from around the cycling industry and by their local community.
