If I ask Google, it says it's an amazing 2.5 hours from my house to the space via bus.
Is anyone travelling to the space from the city, or better, from Queanbeyan? If so, can I have a lift? The one constraint is you'd have to fit a wheelchair in.
Adam, have you had any luck getting a lift? Which day/days did you plan on going to MHV? I don't go often myself yet but I'd like to help you out if I can.
