This is the BEST O scale L/O I have seen.
I bought the CD, If you want a private tour, all it cost is $60.00 Can. between a small group thats penuts.
They do have show dates advertised.
Aberfoyle was also covered in a British O scale magazine -- the builder was positively embarrased by the gushing praise.
Look for the Canadian Association of Railway Modellers site.
The Orangeville (Bruce Division link in Will's post above) layout is really impressive, but is no more . The owner is moving across southern Ontario and will resurrect the layout in his new home. ETA is a few years...
