Blimey, how many months since my last update? Must try harder
Anyhoo, to prove I'm still alive here's a piccy...
Added a building using some bits salvaged from the last layout, with walls made from that pizza base foam scribed with a screwdriver to look somewhat vaguely like stonework. Other than that just some balsa for the ladder and to support the track above the rocky bit.
Will try to make a bit more progress soonishly...
