Jeff Rulifson

When I hike by myself, I carry a Spot satellite personal tracker. You can see where I have been on my Find Me Spot shared page.

Jeff is a nickname. My formal name is Johns F. Rulifson. When my granddaughter was a toddler, she pronounced Jeff as Zeff. As you will see below, it stuck.
