Are there any hidden chests in Sanctuary?

Since Sanctuary is basically the new New Haven, I was wondering if there were any secret chests in the city that are farmable as they were in New Haven for Borderlands 1. I know there is supposed to be an NPC that hands out free loot but I don't know where he is at (I guess that technically isn't a chest >.>). I tried to hop around and didn't really find any, but I could have easily missed them.

The answer is, there are none.

At least as far as I know, and I did search very very closely. I went to every corner, inspected every wall, jumped on top of the highest roofs, did my best to look at every angle and did not spot any chests at all. You only find those small boxes with money inside, and one of those usual "vault" secret sign which I think gave me a badass point.
