On his first day as a Habitat for Humanity volunteer, Clifford A. Popejoy was offered the choice between wiring or installing insulation. It took no more than a nanosecond for Cliff to pick up a coil of Romex and start pulling wire. Since then, he's become the Sacramento, Calif., affiliate's wiring-crew chief and a licensed electrical contractor specializing in "old work": troubleshooting and upgrading the wiring in existing houses and commercial buildings. When Cliff's not working, he often can be found hiking or scrambling in the Sierra Nevadas or the Rocky Mountains.
