...a legendary and two e-techs out of the last three chests I opened.
I got a Gunnerrang out of the car trunk chest at Avie's Camp in Sawtooth. Then I hit the red chest in the elevator shaft and got a Splasher Blashter. And finally on my way to the Boneyard I opened the Hyperion weapons lockers on the bridge out of the Eridium Blight and got a Dart.
Now two of those weapons suck and have already been sold but I'm liking my chances of finding more good stuff.
