Then why don't we get together, you and me and Molly, and start roughing out what we want to do with the space. Portal itself isn't gonna be movable but we presumably have more flexibility around it, modulo the lakebed. Kill/spill is all well and good but when we want it to happen, not just because we wanted to change up the space.

Once we have that, the rest of the planning can be informed based on what we come up with.
