I've played BL2 a few times and every time I get to it I sabotage the hodunks then sabotage the zafords and then my only objective is "respond to zafords call" and I can not figure out how to side with hodunks.
I know it's probably a dumb question but after about 6 play through I've never been able to side with hodunks and really wanna farm for Maggie but I probably won't be able to if I side with zafords.
After a couple of missions, you have to seek out the exclamation point for the next leg of the quest (this happens a few times). I don't know why they didn't just make this one keep updating with the next step like most every other quest in the game, since it makes it difficult to find the next step if you aren't paying enough attention.
I think your next step is in the Hodunk area. Just check your map for undiscovered quests.
