I just did this for my trees and houses last night. Now to sort through them, and make a pick list of favs. Old dogs can learn new tricks!
I was inspired to organise my Signals last night - it took about 2 hours to do - and I ended up with 2 separate areas for Colour Lights and Semaphores. It was worth it though as I discovered a lot of things I didn't know I had. Now all I have to do when I need a signal is wander round and pick one.
