Hmmm...have you tried camping outside in Trynton? What with Hogars and everything, there should be some good xp there.
The longer you camp, the more likely you are to be attacked by hordes on the road.
How about the retro dungeon in the graveyard?
Or, for a REALLY fun experience, how about hanging out and sleeping in the Ratkin tree for a while after you kill the breeders. There are some really large groups there (and they drop some good stuff, too).
You'll also pick up some good xp if you move on to the swamp (although you'll probably be sick of the sight of mosquitos [img]tongue.gif[/img] ). The cool thing about the swamp is that there never seems to be a shortage of battles if XP are what you're looking for.
It's hard to give other suggestions without knowing why you're not just moving on to the next step.
