State Route 35, generally known as Skyline Boulevard, is a two-lane road running mostly along the ridge of the Santa Cruz Mountains from Highway 17 in Santa Clara County to San Francisco at State Route 1. Because of its high elevation and location, it is one of the few places on the southern portion of the San Francisco Peninsula from which the San Francisco Bay and the Pacific Ocean are both visible at the same time. It also provides scenic views of the Silicon Valley Metropolitan Area. 

This historic and protected scenic corridor is the location of our workshop. Here on the property of John and Cathy and family, the workshop will focus on well balanced instruction of the skills required to install a treehouse platform using O2 Treehouses's Tetratruss platform system.  

Arriving at the lovely home of John and Cathy M. Park on Friday morning, you may park anywhere along Skyline Blvd, or find a spot in the driveway. If you would prefer set up camp early and arrive the night before, great! Simply let us know on the signup form.
