Hike for Discovery is a fund-raising arm of the Leukemia & Lymphoma Society that combines adventures with raising awareness and research dollars. A co-worker of mine did a Grand Canyon hike with the group a few years back.
Here’s a link to the organization’s South Bay chapter. Current outings: Yosemite, Rocky Mountain and Grand Canyon national parks; and Kauai, Hawaii.
This is one of those “if you’re going to be out hiking anyway…” kinds of opportunities we all oughta be participating in. Here’s a blog belonging to a woman getting ready for a Kauai adventure.
