Hi Emily. You might ask the fire dept. Rescue guys with confined space or cliff training might give you locations. I think Upper Chico Creek has some short hops. Below Berryessa Dam, across Putah Creek are some cliffs I used to go in the sixties with ROTC Rangers. You have to swim or zipline across PG&E's cable. We used to go off the roofs of 5 story dorms. Grain elevators, high tension towers, cranes, ladder trucks, string lines across powerpoles. I was airborne army in early 70's, nothing beats rapelling off the skids of a Huey. Ahhhh, the good ol' days...I'm just south of Gridley, not a Stagger but a solitary camper in the suburbs usually 4:30 at F or G Streets usually in sight of the pottybank.Come on by for a shot -o-tequila or a cold beer.
