If you have the machinery for it, it's not difficult to navigate.

There're a few crates in there that have useable rations. Mind you, they're probably long expired - three years is a long time to actually be there - but so long as they're still edible, then that's all we need.

I don't know how many of the crates are still there, but the last time I went with a buddy, we found a few things including seasonings and the chocolate.
