Depends on how ready Cao Pi is. Maybe after, unless enough people want to help with either, in which case we could probably split into two teams. If we don't find wheels for the cart and can't work out how to deal with the locks, then we're walking and I'd like to make sure the people here who don't feel safe enough going down to the station have access to everything in it before we take off into the tunnels. Just have to balance the risks.
