Thanks-Mark
yeah, prisoners are only in the lock down. You just need to find that jump again. It's just a bit past the World's Largest Bullet. For skags and midgets, any will do. I got mine the last time farming Road's End on my way back to kill Knoxx again.
It took four trips to finish the 100 midgets. They start at the gondola ride and will take you to the back door of Ajax. Another nice kill. Don't miss the chest by the on ramp guarded by about six badass skags.
Just bring a good fire weapon. Hellfire, Firehawk are decent. A pestilant crux shotgun works well too. I know, I said fire and that's acid, but it melts them doggies down.

It's normal you have to kill : Prisoners, Midgets and Skag, when done go back to see him.
All that stuff can be done in Sunken Sea :
For the Midget you'll have to jump with a racer at the first piece of road you see when you arrive at Sunken Sea (The one close to the Midget that gives you the Motorhead Quest) and you'll arrive at some stair to descent a little Midget Village, down to it you'll have plenty of Skags too. The Prisoners at indeed in the Prison ;)
