The one with the electrical barrier has a switch guarded by a Badass Nomad I believe. I think the next large room you come to has an exit to this area. Never got the chest in the jail cell. --- "The only good is knowledge and the only evil is ignorance."-Socrates
There is a control room above the entrance to this area. find the ladder near the end of the room, climb. Then get one chest at end of catwalk. back track to where you can jump on large pipes, and walk over to control room. Go in the room and activate all the switches marked with corresponding numbers to the cells. --- GT: Angry Keith J
A trick with the first barrier, you can shoot out the fuse box from the same room. Just turn around, look up at the window, and you should see the outline of the fusebox to the right. --- "Because I realize I want you. Guts." "....... Are you a ****?"
