White-Water Rafts

Inventor Gordon Holcombe once worked in the commercial aircraft evacuation business. When the first DC-10 jumbo jet came out in 1971, he realized the curved slides used for emergency exits could be adapted to make river rafts. He founded raftmaker Maravia, which subsequent owner Doug Tims moved from California to Boise, Idaho, in 1985.
