Strapworks sewing straps began with a love for rafting. I founded the rafting program as a sophomore at UC Davis California in 1974. In 1975 Donna and I started Sierra Whitewater Expeditions Rafting Company, taking guests on river trips all over California, Oregon, and Washington.Strapworks sewing straps began with a love for rafting.
