Our club, the Smoky Mountain Model Railroaders is 12 miles away and due to the roads (many quick curves) about a 25 minute drive. That's the only 3 rail layout anywhere near here. One member lives down in Greenville SC but has a cabin a few miles from me here in Maggie Valley. His wife has had a lot of health problems this past year so I've hardly seen him recently.
Otherwise, there are scant few 3 rail guys locally...
