The number of youths participating in the team experience of the Challenge Course at Camp Long has been going up, up and up! King County Parks partnered with Seattle Parks, and the Washington State University Extension 4-H program in providing a $50,000 Youth Sports Facilities Grant to build the expanded challenge course.

In 2011, the Challenge Course served 299 participants. In 2012, 802. As of the end of September, 2013 over 2,100 people participated in the Challenge Course, and in 2014, 4000 participants are expected.

In October 2013, Camp Long became the first 4-H Challenge Course in the state to deploy a new pre and post survey tailored specifically for adventure education participants. The survey is designed to evaluate post-participation behavioral changes in four areas—teamwork, decision-making, communication, and self-efficacy. In the spring of 2014, a report from WSU on the data collected is expected to make recommendations on what students are learning and how the Adventure Education program can improve.
