Forum:Bounty board outside earl's scrapyard

I noticed, outside Crazy Earl's scrapyard (I think in rust commons wast) there is a building with a gun shop and a floating holographic bounty board sign.

I've played through 2 times (ok stopped at janus town on my second play through when I hit 50) and am on a new char, and have yet to find a use for it, or a way into the building.

even the map shows a bounty board there.
