Just fyi, there's a diagonal tunnel that heads from Temple Station to the mine and a N-S tunnel that goes from the mine to the UFO, plus some assorted burrowing that leads from the tunnels into a cave system underneath that area. No current surface structures that I know of though.
It'd be cool to have something over there, and it's not
that far from BP.
Would the land W of Olde London be big enough? I know I keep bringing that area up when people are looking for land, but it's just such a nice piece of property (and relatively flat) that I'd love to see something neat go up there.
